You're fucking a girl with a condom, when you blow your wad in it take it off and smack her with it. Thus pissing her off but giving yourself a very good laugh.

(correct definition) When a girl fills her mouth completely with water and proceeds to suck your dick. You then blow your load in her mouth and give her cheeks a big ole smack and pop that mofuckin water balloon. Hilarity ensues.
I water ballooned my girlfriend because she lost a bet and now she isn't speaking to me but I don't give a shit because I water ballooned her.
