We're Beating Dad Up

Tony and I drove separate to McAllister's today after church because Micah and Blair had cheer tryouts in Sellersburg this afternoon. When I turned into the parking lot, here's the conversation that was going on:
Sulayne: I don't see dad behind us.
Rhett: We must be beating him.
Blair: We're beating dad up.
Micah: Blair, don't say that. That means that your body gets ripped apart and it kills you.
Rhett: Micah, no it doesn't. Tell her mom.
Sulayne: I guess if someone beat you up it could kill you. But we just meant that we are going to get there first. Blair, no one is getting beat up.
Blair: I know ...I was just teasing.
