I've had to deal with Slicksilver555 over Steam chat and in Monster Hunter 3.
All he did in the chat was whine about his imaginary girlfriends and try to make fun of me. Wait, he also whined that the $40,000 car he was getting wasn't the exact type he wanted. He was absolutely worthless in MH3. We ditched him he was so loving bad; it was easier to fight the boss monsters without him around.
