Rocket plunger

When having anal sex with someone and instead of ejaculating you pee. Resembling a pump up water rocket.

My girlfriend told me to pound her fartbox and I slipped her the rocket plunger

Plunger arm

A junkie with a ton of track marks

Jack- Dam who’s that new chick she is so hot

Rick- No man you don’t want to go there she’s on the needle , she got crazy plunger arm

Plunger flush

When you take a dump that requires a plunger in order to flush the toilet

Omg. All that Mexican food made me have to take a plunger flush.
