The PC alternative to using "gay" as an adjective to describe things unrelated to homosexuality.
adjective-lame, silly, waste of time, annoying, etc.
Especially useful over email and IM until your friends are all convinced you are using the PC spelling in your mind when you speak in regular conversation.
ex: My boss won't let me out early today, even though I freaking worked a 24 hour shift yesterday. It's so geigh.
Someone who is "geigh" is usually homosexual, it is loosely linked to the word "gay" (male homosexual) although it has, albeit rarely, been known to be used with reference to lesbians (female homosexuals) as well.
