Replying to What's 4bi9 stand for???

the only thing I could come up with is four bisexual dudes, is that right? Is this like a university of utah sanctioned bisexual club just for guys? Anyone else have any ideas of what 4bi9 stands for, actually 9 stands for women right? so four bisexual chicks? that sounds much better than four gay dudes... then again i saw some guy with a 4bi9 shirt on and he was definetly gay, he was even tapping his foot in the mens room and looking in all the occupied stalls
