When describing an event that just happened in that the event wasn't special enough to be considered fucking awesome but at the same time it wasn't as horrible to be considered okay or good, but just enough to be slightly attractive enough to be remembered.
Eli: Dude, did you see that dunk LeBron did last night against the Wizards? It was fucking awesome!
Matt: It was sexy kind-of at most man, it wasn't that special.
Tyrell: Dude, did you see me tackle that kid?
Nick: That was totally sexy kind-of.
Tyrell: I know man, that's gonna be the last time he makes fun of me.
