look up any word, like swag:
 
1.
The after-affects of eating a large burrito from Chipotle or Q'doba. The burrito is so heavy that it forms a large lump in your stomach that you feel, and sometimes, see.
Dude 1: "Hey dude, want to grab dinner?"
Dude 2: "No way man, I ate at Q'doba for lunch and I STILL have a burrito baby"

OR

Girl 1: " OMG, i am so full!"
Girl 2: "I know, check it out, I have a burrito baby."
