Since some definitions here are a little old, here's the 2010 edition to the definition of "role play"
A kid, usually from middle school to young adult (23 is usually the cut off age now adays) who use someone's pictures, such as a site model, actress, artist, etc and create a character from a book series, TV series, or they start a character from scratch.
Role players are usually hated, but many people (Including role players themselves) think that the perpose is the profile editing, making layouts, editing pictures, creating a story, etc. REAL role players intentions are not to steal peoples pictures and claim to be them. A lot of role players actually ask permission from the person they take pictures from.
I'm not siding with a role player or with a person against role play. I've very nuetral on this topic. But role players are commonly mistaken for fakes. Hopefully I've helped fix that.
