A pee-ka-pooch occurs when a male or female wearing an unfortunately small shirt jerks their upper body causing a protrusion of a flabby pooch. When the upper body returns to its relaxed state, the flabby pooch quickly hides back under the shirt.
Dude, did you see that girl?! She was dancing to some Beyonce, and when she put her hands up, her peekapooch said hello.
