A deeply intense orgasm that causes the entire body to spasm and clench for an extended period of time. Often take minutes to recover from. Can feel like a minor death. Usually comes from a period of orgasm denial or long building orgasm.

Get the Screenshot Omug. When one is struck suddenly with the urge to go #2 in an awkward setting and needs to find a bathroom immediately.
After the sorority wings eating contest I had to go extreme-o so badly but there were too many people in the sorority house and I had to go across the street to the freshman dorm to find an empty bathroom.
