B.S.R.M.
A Butt Sauce Removal Mission is when your butt is dripping like a broken faucet and you have no choice but to go to the bathroom and hope no one sees you.
I did a B. S. R. M. during a movie and had to leave the theater.
My B. S. R. M. was so bad I had to take a shower after.
I did a B. S. R. M. in my car and my friend laughed at me.
