This causes the vacant area for the testicles to do as they please to become occupied by the thighs. This causes the room for one's balls to become blitzed. A few warning signs which often come before a ballroom blitz are "Is someone sitting here?" or "mind if I take a seat?".
Mike: Hey Tim! How's it going? Mind if I sit by you?
Tim: No disrespect Mike, but I'm not just going to let you blitz my ballroom like that.

"Just had to rearrange both of my vegetables. These new undies are giving me serious grief."
"Ahhh, the old Ballroom Blitz. Well wash your hands before you eat any more popcorn chicken."
