Long Island Finance Fuckboy

This is a guy from Long Island, probably studying finance, and a total fuckboy.

You can spot them with the graphic tee, athletic shorts, some sort of trending sneakers, and obnoxiously long white socks. Alternately, Crocs.

They also sometimes Juul, because they think it's so cool. Occasionally, they're in frats.
Girl: "isn't that guy cute?"
Girl 2: "No, he's totally a LIFF."

Professor: "What made you study risk management and finance?"
LIFF: " My Long Island dad."
