To be honest the only true fire way to tell what it is is if it has a COCK or a CUNT!
Eyes have nothing to do with shit, sorry but its the truth. You could be wielding a 45" wrench, have hair on your face like a white rasta in BK, beat your wife, shit 12" peanut busters, fart sounds that echo retarded bears, jump over cars while beating on your chest, milk cows with your teeth, chop down trees with butterknives, shoot at dragonflies with spit, burn ants, fuck your mom... None of that shit matters, the only true fire way to tell is lifing up the skirt or pulling down the mother fucking jock strap.
