habbeda
A loud, angry noise you make when you're too tired to think and don't want to talk.
Bro: 'What did you eat for breakfast?' Me: 'Habbeda!' (with a frown)
Boss: 'Why are you late?' Me: 'Habbeda!' (while eating a donut)
Classmate: 'Who's your crush?' Me: 'Habbeda!' (while staring at the ceiling)
