In the gaming community, "Fixeh" is used to describe someone who pays ridiculous amounts of money for an incredible computer, and then overclocks it, causing it to melt. The average "Fixeh" has an IQ roughly equal to that of a bag of wild berry skittles.
All "Fixeh"s are closeted homosexuals, and may or may not be Jewish, depending on the context.
You just melted your ten thousand dollar computer? What a fucking Fixeh.
