fag-um

Acronym for fat ass gay matt. This describes your typical friend named Matt, especially if they are extremely anal and somewhat portly.

F.A.G. Operon

The F.A.G. operon is an operon, or group of genes with a single promoter (transcribed as a single mRNA). The genes in the operon encode proteins that allow an otherwise heterosexual male inmate to engage in homosexual activity due to the total absence of females with which to engage in sexual behavior.

Dude, I don’t care how desperate I get, I could never have sex with another guy. “Second Person” Hey I thought the same thing until I went to “the pen” for 10 years and the F.A.G. Operon kicked in!
