naffer
A fan of a CS player named Naf who yells 'naffer' in Twitch chat like it’s the last word in the dictionary. They spam it so much it’s like a curse.
"Naffer! Naffer! Naffer!", A Twitch chat during a big play
"That naffer just made me lose my bet.", A friend after a stream
"I’m a naffer and I’m proud.", A guy in the comments section
