Any person whose fandom for a certain
thing takes the form of a constant irritating sales pitch for those unfamiliar with or not already into
said thing.
"I was in a CD
store, trying to get my friend to buy this
folk-rock record, when some Emo 'salesfan' overheard us and butted in, trying to tell us that rock was dead and how if we
REALLY wanted to hear good music, we'd check out the ________ band."
