2.
When your girlfriend (or boyfriend in some cases) tries to take your attention off what you're doing to make her the focus of your attention.

3.
When you're strolling down the land of make-believe and suddenly a ferocious beast with powers far surpassing your own attacks you out of nowhere- only this time it's in real life. When your girlfirend wants some attention, she'll get it one way or another.
Player 1: Hey, after this run, I'm gonna have to bounce.

Player 2: Why?

Player 1: I've got a little girlfriend aggro here.
