This one is pretty silly but me and my gf had a good laugh when we saw it. It was a while back in Betfair Poker. The guy's screen name was "50pence" and his location "da hood".
there used to be a guy on FTP named douche. He ran well and many railed him when he was winning everyone would say nice hand douche tid douche stuff like that I thought it was classic
i was playing a sng on UB like a year ago and one guy was named a potato chip.. it was only funny when he won a pot because in the chat box it would say "a potato chip wins 300"
