FATT 

This term is an abbreviation for the phrase "Funny At The Time." It implies that a joke just made might've been FATT, but definitely has no humor now. It is somewhat insulting, and therefore, should only be used to describe the jokes of people you don't like.

Fatt Melty 

A custom made Bacon Cheeseburger using Grilled Cheese Sandwiches instead of hamburger buns. An ultimate delicacy.

We were hanging out about to watch UFC, so we fired up the grill and griddle to make Fatt Meltys for everyone.
