Gaaaar
Gaaaar is like a pirate who ran out of rum and also got yelled at by his captain. It’s the sound of pure frustration coming out of your mouth like a volcano.
GAAAAR! My math teacher gave me a pop quiz and I didn’t study!
GAAAAR! My dog ate my homework and now I have to write an essay about it.
GAAAAR! I got a D on my math test and I didn’t even do the homework.
