The Moment: At the VH1 Hip-Hop Honors in October 2007, Lupe forgot the words to part of a verse on A Tribe Called Quest's "Electric Relaxation" and later revealed that he had never been a big fan of Tribe's catalog or their classic 1993 album, Midnight Marauders. The Internet deemed it "Fiascogate."
The Reaction: Tribe fans were—of course—super pissed off at Lupe for flubbing some of the lines and attacked him for not doing his homework beforehand to make sure he paid proper tribute to Tribe.
Did It Help or Hurt His Career? HURT! Lupe worked hard to make sure that (most) fans would forget "Fiascogate" by the time 2008 rolled around. But it's definitely still a blemish on his overall body of work.
