Three pronged attack 

When three mates get together to form a strategy on a night out, usually but not always to take down the hottest girl.

Also known as a TPA, with a hand sign showing the three middle fingers.

Boys, strategy for the evening will be a "Three pronged attack"…..first in clear the way, second in make contact and third in take it home. No paper trails.
