baaaaaaa - When you're too lazy to think of a real scream but you still

When you're too lazy to think of a real scream but you still want to yell at the universe.

I got a D on my test and just went BAAAAAAA in the hallway.

My dog barked at the mailman and went BAAAAAAA like it was a war.

I saw my crush and screamed BAAAAAAA because I was too nervous to talk.
