Theodore Seville in the fourth CGI/live-action film, Alvin and the Chipmunks: The Road Chip. The song does not appear on the official soundtrack for the film.
I like big butts and I cannot lie
You other brothers can't deny
When a girl walks in with an itty bitty waist
And a round thing in your face
You get sprung, wanna pull up tough
'Cause you notice that butt was stuffed
