A word you throw out when you're too lazy to think of a real sentence and the silence is making you feel like you're going crazy.

'Bababooeey' was the only thing my friend could say when we were stuck in the elevator for an hour.

I said 'Bababooeey' when my dog ate my homework and I had no idea what to do.

The whole group said 'Bababooeey' when the teacher announced the final exam was tomorrow.
