Jarbody
Could be confused with bodyjar but is typically used if someone can't come up with a good insult so they combine 2 things that come to head. It seems like a fat joke but actually is not since it is not typically given to a specific person. Therefore if you use this you are saying a made up word.
That kid is honestly such a jarbody.
Your honestly such a jarbody.
