look up any word, like ratchet:
A person who wants to have sex all day long. They are either thinking about it. Working toward getting it or having it at almost all times!
I was rubbing Alicia's shoulders...next thing you know I've got my pants off getting a smoker! That girl is a sex t-rex, we fucked all night!
It wasn't until the next morning I realized how many miles of cock had already beat that moose knuckle into submission!
