Jeremy Stephens Finally Fires Back at McGregor's 'Who the F--k Is That Guy' Quip

"Who the f--k is that guy?"

With that one quote, Conor McGregor transformed Jeremy Stephens from an anonymous UFC mid-card veteran to the butt of MMA's most popular one-liner. While it isn't the most clever line of the double champ's career, the MMA universe hasn't forgotten about that zinger...and neither has Stephens.

Nearly a year removed from that fateful UFC 205 press conference, L'il Heathen exacted a small bit of vengeance on McGregor on Twitter.

Granted, a 12-month-in-the-making "your mother" joke isn't especially impressive but it's a long-overdue counterpunch from Stephens, who has been loudly silent about McGregor ever since. Coming off an important win over Gilbert Melendez at UFC 215, the 31-year-old seems to be aiming for the top...and that's a good thing.
