A cross between making out and french kissing, which are already the same things but sound awesome when mixed.
Girl 1: SO how was the movie?
Girl 2: I'm not sure, i was frenching out the entire time with my boyfriend

Get the Frenching Out mug.
Behaviour that combines the french hello and french goodbye and even stretches beyond.
Someone attends a dinner party and ignores all guests for several hours. Then he leaves the place without saying goodbye to anyone. That´s a proper french night out.
