A diamond shaped street sign indicating bumps in the road ahead in an attempt to slow drivers. Also, the act of having sex in a very fast paced jack rabbit like motion.
Slow down! The speed humps ahead will mess up your car yo.

We were running super late to the fiesta so Keisha and I had to speed hump in the shower yo.

Cory is such a speed humper.... we were done in like eight seconds!
