Bonersaurs can be used to describe someone instead of: dork, tool, or any other characterization of someone who is just lame.

A person, usually male that walks around waving its arms and makes obscure noises. And they normally have very smelly feet and throw spoons.

It sometimes dances (usually to mid 2000 pop hits, notably "My Humps") and waves its arms around like it's having a seizure.
"oh man look at that guy trying to dance up on that chick."

"yeah, what a bonersaurs."
