A chopper whopper is where a man grabs the base of the shaft and makes a chopping motion up and down. Hence the "chopper". For it to be a true whopper, the member must be large.
Jared was on a date with Tracey, and as a last ditch effort, pulled down his pants and shook his huge dick up and down in a chopping motion. Tracey was impressed and asked what was that. Jared replied, "that's a chopper whopper."
