It wasn't the most annoying thing he said, just the funniest. With every pull he was like "I'll off-tank such-and-such!" After every pull he would say "Like my off-tanking? :)" Keep in mind this was a WARLOCK. I wasn't aware standing 20 feet away dropping DOT's, then hopping around like a duck with its ass on fire while waiting for the plate-wearers to pull crap off you counted as off-tanking but whatever. He was so conceited that I started whispering my friend in the group making Chuck Norris style jokes about him. "He doesn't lock summon, he grabs the two locations and physically crushes them together!" That kind of thing.
