FBOI

Gen Z Slang

Definition

FBOI: shorthand for “fuckboy” — a self-centered, emotionally unavailable guy who strings people along for attention or casual hookups and avoids commitment.

Examples

"I’m done wasting time on that FBOI who only texts after midnight."

"Her friends warned her he was an FBOI, but the charm made it hard to notice the red flags."

"He keeps breadcrumbing you—classic FBOI behavior: lots of attention, zero commitment."
