Say some girl likes a guy at a club, so she follows him around and tries to talk to him at every chance she gets, even though he is clearly uninterested.

"Look at that poor girl, she's doin too much!"

Also, girls and guys who are obviously trying way too hard to act cool or look good.

"Did you see that girl with her titties hanging out for everyone to see? She's doin way too much!"

"Daaaaamn, Booshanadaqueeda be doin' too much wearin dem new chucks!"
