Urban Dictionary defines a bromance as "a close, non-sexual relationship between two males" that can sometimes reach "such a point where they start to seem like a couple".
This complicated, heterosexual relationship was highlighted in John Hamburg's 2009 film, "I Love You Man" starring Paul Rudd and Jason Segel.
This form of homosocial intimacy has become very popular in American culture, likely not understood by the rest of the world.
Nonetheless, bromances are very entertaining to those outside of the relationship.
It should be a given that the NFL, with all of the high-testosterone players, would have plenty of bromances that not only provide fans with entertainment, but provide teams with chemistry as well.
Here is a list of the most entertaining, inexplicable male relationships in the NFL.
This barely made the list because it is between a player and a coach, but it was just too good to pass up.
Drew Brees and Sean Payton are the two most important pieces to the New Orleans Saints. Without either of them, the Saints would not be Superbowl XLIV Champions.
Brees and Payton's relationship is not just on the field or in the locker room either, they both claim to be close personal friends away from football as well.
Assistant coach Carl Nicks said this of their relationship, "I really think it's unlike any-other quarterback-coach relationship in the NFL, just the way they're always on the same page all the time; and the way they kind of feed off each other."
Tight end Billy Miller says, "they make each other right."
I'm not just making this stuff up either, it's all from Mike Triplett's nola.com article "Drew Brees, Sean Payton have shared vision for New Orleans Saints." http://www.nola.com/saints/index.ssf/2010/01/drew_brees_sean_payton_have_sh.html
Though the Brees/Payton bromance is not as prolific and outlandish as others, they still deserved to make this list.
I'm sure that I'm not the only NFL fan that has, at some point, wondered if Pat and Kevin Williams of the Minnesota Vikings are actually brothers, or if its really just good press to call them the Williams Brothers.
If you haven't figured it out yet, they are not actually brothers.
The "Williams Wall," as it is known, has been the dominant force and face of the Vikings defense since 2003.
Between 2003 and 2009, teams could not run the ball against the Vikings.
Pat and Kevin don't routinely show their affection for each other, but we all know it's there.
The boys do everything together, even fail drug tests. In 2009, Pat and Kevin Williams, along with several other NFL players were under investigation for the use of a banned diuretic, that could be used to mask steroids.
Let me ask you something, do you think that a 6'3", 317 lb. defensive tackle would need to use steroids? Or, could it be possible that he just needed to lose a couple of pounds?
I'll let you guys be the judge, but regardless of the drug testing, Pat and Kevin Williams' relationship was enough to land them at the number four spot on this list.
I realize that this is technically Bro-cest, if that is actually a real term, but these two Southern-Brothers show more affection for each other than I have ever seen with any other siblings.
Seeing Eli and Peyton together is honestly nauseating for me. Besides Venus and Serena Williams, what other pair of siblings, who are also professional athletes, have their own set of commercials together?
I mean for heaven's sake , they had a televised Oreo eating contest together.
I don't know two grown men that have more fun with each other an national television more than these two gentlemen.
It could be worse I guess, we could be constantly hearing about the "sibling rivalry" between the Manning brothers.
I mean yes, they both have Super Bowl rings, but everybody knows that Eli will never be as good as his big brother. So yeah, I guess it's okay for him to look up to big bro a little bit.
The Manning brother bromance is #3 in the NFL.
Side Note: Aren't they cute with their matching shirts in the picture above?
Terrell Owens and Chad Ochocinco, by themselves, have massive - like planet sized - egos. Put the two together and you have a level of arrogance and cockiness of epic proportions.
The two have compared themselves to Michael Jordan and Scotty Pipen. They have compared themselves to Batman and Robin. They even refer to themselves as the collective "T. Ocho."
This relationship all started on VH1, when the two had separate reality shows that played back-to-back.
Ocho's was called "The Perfect Catch" and Owens had the "T.O. Show."
When Owens' contract with the Buffalo Bills was up after 2009, Ocho urged him to come to Cincinnati.
Every day from that point has been a new day full of Tweets, smack-talk and antics, enough to entertain even the grumpiest of fans.
As if it weren't enough, the two also started a joint television program together: "The T. Ocho Show," which plays on Versus.
We all will wonder if the relationship will be allowed to continue in 2011, or if the two will move on to different, greener pastures.
Their crazy bromance was probably the only thing that Bengals fans had to look forward to in 2010 and was enough to land them at number two on this list.
If their relationships with females continue to fail as much as they have on their TV programs, at least they'll have each other.
The relationship between The Dallas Cowboys' QB Tony Romo and TE Jason Witten is the reason I made this list.
The two share such affection for each other that words alone are not sufficient.
Romo practically only throws to Witten when the two are on the field, which is probably the reason why Terrell Owens wanted out of Dallas.
The two can be spotted on the street together, shopping, getting food and drinks and even just hanging out.
Romo's failed celebrity relationships were probably just a cover-up for the love that he has for Witten.
Like I said, words alone are insufficient, so here's a video to truly show you the level of affection that these grown men have for each other.

Romo and Witten Share a bromance like none other. Their love and affection on and off the field has landed them at the top of this list.
