Trumped-up trickle-down

A variation of a golden shower, this lewd sex act involves paying underage prostitutes to urinate on an object which represents your enemy or rival.

Bobby also seems to want Vanessa, so I grabbed his letter jacket while he was distracted to give it the ol' Trumped-up trickle-down. Can I borrow a tarp?

Bottoms down

Bottoms down means that you are done doing shots and do not want to end up with a six star hangover.

Annie's friends were taking shots one after another and Annie did not want to get involved, so she said bottoms down.
