the feeling of disappointment a guy feels when a girl claims to be a gamer to get attention from him, but then leaves him hanging when the time comes to actually play something. like blue balls, but with gaming instead of sex.
Jenny said she likes to play video games, but every time i suggest we kick on the xbox she runs off and leaves me with a major case of blue thumb.
