The act of deceptively telling a slutty hoe you have lost your phone by using your buddies phone, via text, so that she believes your new number is his number.
They are choloing that hoes number because she went crazy after giving Clint a BJ behind the dumpster of Red Lobster.
Boris: Why do you always grab your phone off your desk before heading to the bathroom?
Bobby: Because why poop, when you can choop?
Boris: Chooping? Ohhh... I get it.
