Travis Scott went mental after a fan attempted to steal a Yeezy 350 Boost off his foot mid-set at a festival in Switzerland.

The fan failed to make off with the Kanye-designed sneaker … but that didn't stop Scott from going berzerk. There's spitting, a water bottle gets hurled, and by the end of it Scott has the Swiss people chanting “f*** that bitch, f*** that bitch!” We know, so unlike the usually calm, neutral country.

The fan guy was removed by security, but not before Scott threw literal shade ... a pair of sunglasses.
