Go over there and check up on things.

You walk over there macho-like.

"Is everything alright over here?" you say in a commanding tone, yet sounding casual.

"Yea-" the guy starts.

"NO!" the girl screams, her eyes brimming with tears. "He's been following me ever since we broke up. Make him leave me alone!"

"Get out of here," you tell him casually.

"No," he says.

"Go!" you command.

"Who's going to make me?" he says.

All of a sudden the moves come to your head. Brazilian Jiu-Jitsu.
