What is Turtle Body?
1.
A significantly obese person, usually a woman. So named for their inability to rest their arms parallel to their bodies, and their shuffling walk.
If they were to fall on their backs, they'd likely be unable to get up.
"So, you think there'll be any hot chicks at that Def Leppard tribute band's concert?"
"Well, there's guaranteed to be a turtle body or 20."
