when some college teams get a hit makes no sense......i noticed tennessee does it alot a few other teams also.......i'm pretty sure some of the players who do it dont even know what it means, just monkey see monkey do, heard a few explanations such as related to the movie gladiator,
I've seen various other celebrations i've wondered if some of them are related to pop/rap singer signs or even dumberm some kind of gang sign mimic?
