When you get so drunk and reckless that you fall on your face and get a black eye.
Dude 1: You were so hammered last night, your eye is pretty bad.
Dude 2: Yea I really hope its not too noticeable by tomorrow.
Dude 1: Trust me, it wont be. You totally got Mackenzied last night!
Mackenzied: define #2
To get Mackenzied is to get roofied without the pill. To add extra alcohol to your friends/date drink without them knowing and getting them extremely intoxicated leaving them wondering how they got so fucked up last night.
Katie turned her back for one second and we Mackenzied her by adding vodka to her Sangria. She had no idea how she got so drunk.
