bounce

To have sexual relations with someone else, usually casually. Bouncing with someone implies reaching home base. More polite than "fuck," about the same level as "bang" or "screw."

"Dude, last night I bounced this random chick I met at a party. Turns out she's my brother's girlfriend. I'm in such deep shit."

"Did you end up bouncing that hot guy you were hanging on all last night?"

"You're pretty hot. Let's bounce."

"Hey baby, you can bounce on my pogo stick anytime!"
