Jay Bilzerian

Jay is a chaotic, oversexed middle schooler whose home life is neglectful and whose imagination fills the gap with increasingly unhinged fantasies. He's loud, horny, weirdly proud of his pillow-humping habit, and desperate for connection even when he's being gross about it. Nick's friend, the group's id, always ready to overshare.

Mantzoukas plays Jay at maximum volume with zero self-awareness, which is exactly why the character lands — his shamelessness becomes oddly endearing rather than just crude. The show lets his absurdity mask real loneliness, so the jokes about his bizarre horniness sit right next to genuine pathos about a kid nobody's raising properly.
