Gahook!
A loud, fake happy yell you make when you’re actually annoyed as hell by something. It’s like pretending you’re excited while your brain is screaming at you to punch the thing that made you say it.
Gahook! I just got stuck in traffic and my coffee is cold.
Gahook! My mom said I can’t watch anime this weekend.
Gahook! My crush asked me out and I said yes, but now I regret it.
