look up any word, like smh:
Used to the same effect as "shut the hell up" by someone who doesn't use the word hell, often little kids who get in trouble for such "cuss words."
Person 1: You're such a momma's boy!
Person 2: Oh yeah? Well, shut the heck up!
Person 1: Ooh, real tough! What's the matter, mommy won't let you say hell?
Person 2: ...SHUT UP!
