The act of kissing someone hard in a public place. Its like a french
kiss, but way harder, like you
don't draw breath and
ram your tongue down the chics throat hard. It attracts the attention of other people passing by.
Wow,
Tristan is macking the fuck out of that ugly chic, she is totally grose.
Nixon is a skinny
faggot, he always macks other dudes, and lets them finger his arse.
Did you see James macking on at the club last night.
