Mac Stabber
A Mac Stabber is someone who will smile in your face, then stab you in the back with a butter knife. They’ll take your spot in line, sleep with your crush, and then laugh at you.
They took my spot in line and made me wait for 10 minutes.
They made my crush break up with me so they could be together.
They laughed at me when I failed the test, then copied my answers.
