baah
A loud, drawn-out, and probably fake sound that people make when they think they're being cool. It’s like a sheep yelled at you and you didn’t do anything about it.
Baaaaaahhhhh! I just won a bet and I’m too proud to say anything else.
Baaaaaahhhhh! My neighbor’s cat just walked on my keyboard.
Baaaaaahhhhh! I drank 10 cups of coffee and now I’m a monster.
