Hashtags come and go, but a few stick around because they truly bring out the awesome from the bazillion bite-sized inhabitants of the social media universe.
I'm talking about those pound-sign-preceded gems that can be counted on to supply an almost endless supply of hilarious words and images on Twitter and Instagram.
A perfect example? #TBT, or "Throwback Thursday."
Mankind is sitting on a gold mine of awkward, irony-drenched or just plain amazing photos from back in the day—glamour shots filled with glowing edges and pensive stares; rat-tailed mullets and Bugle Boy apparel.
What better way to foist your Kid 'n Play-inspired flattop on the masses than via #TBT?
And for sports fans, #TBT is a great way to see your favorite athletes show off the best of their out-of-style, but far from out-of-mind looks from yesteryear.
