This folk term refers to the “free Lyft” given by USC at certain hours. Lyft is a popular ride-sharing app, and USC partnered with them to give free rides to students to help prevent drunk driving. My friend and bandmate mentioned the term at a rehearsal. I asked her when she had first heard this word. ‘A’ refers to my friend, and ‘B’ refers to me.

A: Um, I started hearing it my first, like, week here at USC. As a young fresh. Um…

B: And it’s just USC campus that you…

A: Yeah. I’ve used it other places, and no one knows what I’m talking about. Or I’ll talk, like, “Oh yeah, I was at this party and then I Fryfted home.” And they’re all like, “What the hell…is a Fryft?”

This implies that the term is only used locally, by people who use USC’s free Lyft. Here is an article that uses this USC-centric slang: https://spoonuniversity.com/place/how-to-take-advantage-of-fryft-at-usc
