Action Bronson -- Grabs and THROWS Fan Off Stage ... Fan Helps Him Do It

You're not enjoying an Action Bronson concert ... until Action Bronson whips your ass and chucks you off the stage -- just ask the guy who got Bronson'd in NYC Tuesday night.

Bronson was doing a record release show at Terminal 5 when the hyped up fan jumped onstage and patiently waited for Action's wrath -- which he got.

Funny thing is ... you can tell from the video the guy LOVED it, and maybe even self-propelled himself off the stage. It's actually become a thing at Action's concerts -- fans crowd surf to the stage, so he can give 'em the ole heave-ho.
