Role Playing: refers to the changing of one's behavior to assume a role, either unconsciously to fill a social role, یا consciously to act out an adopted role I'd say= anything from tv shows to عملی حکمت to video game characters to someone they know. RPing (reminds me یا raping XD )is not to be confused/mistaken as immitating someone. I don't role play but have fun with ppl who do ^^
