To be in a short and unsatisfying relationship with Taylor Swift, only to have a write an insulting song about you after you break up.
Person 1: Did you hear? Harry Styles and Taylor Swift just broke up! He's totally about to be swifted!!
Person 2: Really? I guess he's about to join the ranks of Joe Jonas, Jake Gyllenhaal, John Mayer, and all those other poor fools who got caught in the witch's trap.
Person 1: Wow, maybe she's the problem.
Person 2: It doesn't matter to her since she gets paid for every guy she swifts
Derived from Kanye West stealing the mic off Taylor Swift at the 2009 VMA's after she won best female video.
being in the middle of an acceptance speech or something similar and having a someone interrupt you to say someone else was better.
"Kanye totally swifted that chick at the VMA's on sunday"
"yeah what a dick that guy was"
