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.

When you're driving and you see speedhumps you go 'ohh damn. not again!' and they really annoy you. Same with a speedhump person.
