A sexual position in which the guy ends up cumming across the chest of his partner. Imagine the letter capital A drawn over your partner's face and chest. Imagine drawing a diagonal line from their mouth to each nipple. Next, get a handjob and when you ejaculate, spread the cum horizontally across their chest as if connecting the imaginary lines described above. This completes the Atlanta Connector.
Guy 1: "Bro, did you practice the Atlanta Connector on your girlfriend again?"
Guy 2: "Yeah man, I was on my A-game."
