Dirty Whiffer
the name of a friend who intentionally sends you a trade involving certain names you both discussed and when it comes time to pull the trigger he adds someone you didn't talk about and blames you for it blowing up.
I thought we were trading Cook, and Berkman for Holliday, Atkins and Fielder, but the Dirty Whiffer added McCann to the deal at the last minute and called it a "Misunderstanding"
