fat pumpkin 

A bong from which to smoke pot.

"Hey, hey. Let's go check out the fat pumpkins at Belmont"
"Yeah man, sounds like a plan."

Fat Matt Plumpkin 

A big for nothing bitch. In their natural habitat they can be found sucking major dick in the Toronto, Oh area… you can often find them struggling to get back up off of their knees due to the fact that they are so top heavy.

“Is that a fat hooker walking down the road?”
“Is it a homosexual cow?!”
“Oh… no. It’s just fat matt plumpkin.”
