Jiffle 

Breakfast for the lazy and/or time-crunched; consists of an Eggo waffle smeared with Jif peanut butter, eaten quickly over the sink and washed down with milk directly from the carton. Pathetic, yet satisfying.

"Dude, did you get to eat breakfast this morning? You look tired."

"Yeah, man, I slammed a Jiffle before I got here."
