I met a kid like that in high school. He'd make a big deal about finding an apple or whatever for his character and claim it made him a Real Roleplayer!!! While the rest of us were going, "We'd like to play too? Maybe get a word in edgewise?" Needless to say, he was only around for one session.I've heard stories of people doing this; its usually perceived as an excuse to "roleplay" everything, with the suspicion its a way to keep the spotlight on them All The Time.
