Tying up the opening of your foreskin and then masturbating while keeping it tied over a longperiod of time until it's full of semen and then giving a girl the biggest facial she's ever received.
Friend: "How'd it go with you and Michelle last night?"
You: "Went great, I've been saving a water balloon all month for her."
When a guy wraps a balloon over his dick, then he jizzes in someone's ass, ties off the balloon, and they fart it out, which usually causes it to pop. Get others involved and it's a water balloon fight!
its when you dont jerk-off for a year or so and you have sex with a girl and you bust a load in a comdom and you tie it close then you hit her in the face with it
dude i didnt jerk-off for a year and i was fuckin this girl and i shot a big load off and i tie the end of the comdom and then i did the water balloon fight to her
