Everlast, the rapper, bluesman, and erstwhile House of Pain frontman, has some caustic words for Republican presidential hopeful Donald Trump about his purported use of the 1992 jam “Jump Around” at campaign rallies.

In a profanity-laced Twitter rant Monday, Everlast (whose real name is Erik Francis Schrody) told Trump to “stop using my song,” warned that a cease-and-desist order was on the way, called Trump several derisive names, and threatened to “smack” him.

He also took aim at Trump supporters, saying he was “honored to have pissed [them] off.”

Everlast comes as the latest — and perhaps most scornful — in a string of artists to admonish Trump for using their music without permission, joining Adele, Steven Tyler of Aerosmith, Neil Young, and Michael Stipe of R.E.M. (Twisted Sister’s Dee Snider did, however, give Trump his blessing to use “We’re Not Gonna Take It.”)

Everlast added that he has “no endorsement of any candidate.” Check out his NSFW tweets below.
