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.
