When Matt came up to visit Jonna, Derek told them to cut out the PDA's. When Bronne brought home a babe, Derek made fun of her vocal stylings. And now that Jasmine's FINALLY movin' on from Pat, Derek's rippin' on her for dating a gay guy. Seriously, WTF is the dude's problem?! Is he a jokester? Or just a total jerkass? Take the poll and tell us whether Derek's a fun-lovin' guy -- or a passive aggressive grouch.
