Place it near the end of a short food or reaction edit, after a normal setup line, then follow it with What Da Dog Doin for a second interruption before Okay Let's Go closes the joke.

This is a very short spoken clip, about a second and a half long, in which a flat, matter-of-fact voice says coke butter cheese in quick succession. The plain delivery makes the three unrelated words feel silly and slightly confusing, and that confusion is the joke. It lands as a tiny absurd interruption that is easy to remember and repeat.
