P.O.P, hold it down.
A stupid phrase from a Vine that came from a dumb YouTube video where a woman said something stupid about why she did something bad. Now everyone uses it to laugh at each other when they get caught doing something embarrassing.
"P. O. P, hold it down!" I said when my mom caught me eating the last slice of pizza.
My friend used it when he got caught texting during math class.
I told my crush "P. O. P, hold it down!" when he stole my snack.
