Mackin' Out 

Taking part in the locking of lips. Commonly known as smooching, snogging, sucking face, etc. Derived from the more well known, and certainly less interesting, "making out."

"Hey Vanessa, I like you. Wanna go mack out in the woods?"

"Did you see those two mackin' out in the hall yesterday? I thought I was going to projectile vomit it was so repulsive!"

Usually written in all caps for maximum effect, this is a smug declaration of quasi-random physical affection with someone of the male gender. May result from HEE HEE PET PET and lead to chin-chap and/or BUMPIN' AND LOVIN' IN THE BED.

Dakota smiled lazily and announced to her friend, "My lips are chapped... from MAKIN' OUT WITH SOME BOY last night!"
