Downtown fun

An alternate to "down to fuck". When you're on a dating app chatting with a hottie and she asks you what you're into, you can say you are DTF. If she asks "what does that mean???" you can say it means downtown fun instead of down to fuck. That way you don't look like such a fuckboy and can salvage the date and the possibility of hitting it.

Renee: So what do you like to do for fun?
Kristoff: I like skiing, traveling, eating great food, DTF, hanging out with my brother and his awesome family, you know... nothing crazy. You???
Renee: Wait, what do you mean by DTF???
Kristoff: Downtown fun, like going out to eat and to carnivals and stuff. Want to go get Boba tea some time?

toilet submarine

Those turds that aren't floaters or sinkers, they bob in-between.

Steve: Dude, check out what just invaded the crapper.

Bob: DAMN!!! That is one huge toilet submarine!

Runny Robbie

This is the act of eating out someone's asshole while the person is taking a dump.

Bradley was in a great mood because Kimberly performed a Runny Robbie on him after he had eaten a lot of mexican food, which gave him a case of explosive diarrhea.
