my friend was over my house a few days ago and we were in the pool.. he is like the funniest kid i no taught me something.. flick your nipple on the tip and count to 7.. after the 7 seconds your nipple should be like rele hard. i was cracking up that he told me this out of NO where.. he is VERY random, but its funny to do when you come out of the shower and are bored
