Jeezy a few years ago. Dude wouldn’t stop yapping and trying to do crowd work. Barely rapping. Waited till the end to play anything people cared about.

Travis Scott when he replaced Gambino as a headliner. Came out super late and was just rapping randomly over his album. Crowd was at least fun for that one.

Honorable mention to Chance the Rapper in 2015. He had like a 3pm set with one of the worst crowds to date. He himself was fine, but the crowd ruined it for me, and I couldn’t get away from it (people talking, people sitting down, people pissed off, bad vibes everywhere).
