Chaids

A disease one acquires from having sexual intercourse on the floor of the fraternity basement while being watched by a brother. Once the disease is acquired, it cannot be cured and all offspring will also suffer from chaids.

Dude 1: where’d you go with that girl last night?

Dude 2: we went in the basement and fucked on the floor.

Dude 1: holy shit, you have chaids.
