After eating 2 burritos, spread a girl's butt cheeks apart and vomit into the bowl-shaped cavity. Proceed to have anal sex, using the partially digested burritos as lube.
I feel great - I just gave that girl a burrito bowl.
When a guy takes a girl to Chipotle to get a burrito. He then takes the Chipotle burrito an shoves it into her vagina. He then eats the burrito while it's still inside her. Good for both parties because they are both stuffed.
Guy: Let's go get Chipotle
Guy: So I can eat a burrito bowl!
