Ok so here are the rules. You're creating a word or short phrase to simply capture an idea for which no simple word or phrase currently exists. This can be a word you came up with yourself or something you've heard people say that isn't commonly used yet.
These can or can't be gaming related.
So here is one I came up with.
"Anti-Fanboy/Fangirl" - An individual who is as committed to hating something as a fanboy is to loving it. Essentially the equal but opposite of a fanboy.
"Man I don't like Justin Bieber's music but you hate that kid so much you come off as an anti-fanboy of his."
"You post as much on the Star Citizen section as much as the actual fans of the game do yet you hate it. Get a life and stop being such an anti-fanboy."
An here is an idea that I think needs one.
If you are married your spouse's family become your "in-laws." "Brother-in-law", "sister-in-law", "mother-in-law", "father-in-law" etc. But if you are simply in a relationship with someone, particularly a long term relationship there is no word to describe their family other than "My girlfriend's brother" etc.
It would be cool to see an "in-law" type phrase arise that describes the family of a significant other you are not yet married to.
