J1 

The first guy named Justin that you met out of the sea of Justins that you know. He is cool beyond all measures, has a pretty big dick, is really jacked, goes to the gym hardcore, and can get any girl you have ever wanted. Usually wears exclusive clothes and is seen with a jewish looking guy as his wingman.

Dude 1 : "who's that guy?"
Dude 2 : "It's J1 with some hot bitches and his wingman"
Dude 1 : "who's that other guy over there?"
Dude 2 : "Oh just some guy named Justin, he's a fuckin creeper...."

J1 

A shared wavelength of chill, curiosity, and connection. When people are j1-ing, they’re syncing up emotionally and atmospherically—no pressure, just presence.

"Her whole mood was a J1 vibe!"
