Bag o' Burgers
A very fat person. Usually greasy too! Eventually the bag is going to get greasy itself because of the burgers inside of it. Burgers are very fattening. They are all taken in by fat people, who then become bags o' burgers!
"Yo, look at that Bag o' Burgers over there!"
"Dude... thats so nasty."
"Dude... thats so nasty."
