baaaaaah
a loud, annoying sound made by kids from loughton, essex to drive their teachers, parents, or any adult in charge absolutely insane.
"Baaaaaaah!" he screamed, because he didn't want to do math.
The teacher was yelling, "Baaaaaaah!" because the kids were being rowdy.
She said, "Baaaaaaah!" because she was tired of being bossed around.
