water balloon 

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.

Chinese Water Balloon 

Two objects, namely one uncircumcised penis, and one other penis gently come together into a tip to tip union. Once touching, the uncircumcised male then proceeds to encapsulate the other mans shaft creating a perfect vacuum seal. Akin to a Chinese Finger Trap, once the seal has been established one of the participants then urinates to create a wee filled water balloon; this is then deposited into the third participants mouth.

Juan and Pablo were both feeling a bit bored so they decided to engage in a Chinese Water Balloon and dump it in Hector's mouth

Ukrainian water balloon 

An uncircumcised man sews his foreskin shut and nuts continuously until the foreskin is full and expands like a water balloon until it pops and the cum splatters everywhere.

Girl:want to try the Ukrainian water balloon

Boy: no I’m circumcised

Water Balloon 

(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.
