A shaddap is when you yell at someone to stop talking like they’re the last person on Earth and you’re the last person who can stand it.
Shaddap! I’m trying to sleep and you’re yapping like a parrot on a caffeine rush!
Shaddap! I’ve heard your dumb stories a thousand times!
Shaddap! I’m not even listening anymore, just screaming at you for fun.
