Top Definition
The opposite of sex drive. It happens when you're sick and you can't really get aroused. You usually need to have a pretty bad cold or the flu to get it.
Dude 1: Dude! Last week I had the flu, and I missed work but I was really bored cuz I didn't feel like watching porn.

Dude 2: But dude, you're addicted to porn and you watch it at least 7 hours a day!

Dude 1: I know, but I had a sick drive instead of a sex drive.

Dude 2: Oh. Sorry dude. That sucks.

Dude 1: I know.
