B.F.o.t.D. - What your body does when it's too full and it can't hold it

What your body does when it's too full and it can't hold it anymore.

I ate too much pizza and my B. F. o. t. D. hit me right after.

I had to leave the party because my B. F. o. t. D. was too loud.

I was trying to walk and my B. F. o. t. D. made me stop.
