A Lenwen is a person who tries to contribute intelligent opinions to discussions around sports topics only to be completely and utterly shot down due to high volumes of poor judgment and a complete lack of perspective.

The term is coined from the avatar name of a frequent poster on ESPN's forums, who has drawn ire for his consistent inaccuracy in predicting sporting outcomes and general inability to see reason.
"I was on the ESPN boards and this Lenwen claimed that Greg Oden would be better than Bill Russel."

Joe: "The combination of Lebron and Shaq on the same team means a guaranteed finals appearance. This is not even debatable."
Jack: "... God you're such a Lenwen... Why am I even friends with you?"
