Polite way of saying shit, poo, a stool.
Abby is making a deposit in the bathroom.
Sometimes you spot someone on the street who you think is very attractive and would like to fuck. However, these hastily made judgements can backfire when you realise upon closer inspection they are below the age of consent. If this is the case then you can instead put a deposit down for a later date once they've matured.
Hi Andy, check her out over there.
Woah! She's a bit on the young side.
True, ah well i'd put a deposit down anyway.
Shooting semen in the butt hole of another. Like making a deposit at a bank.
I gave the girl I met last night a deposit.
Bro: Dude, when you gonna break in the new place?
You: I Just settled up, what you thinkin'?
Bro: Man, three words, keg, KY, and hot bitches.

Bro: And a slip n' slide
