Arc Fault Interrupter, a type of electrical protection device that senses an arc between live conductors and ground, and will interrupt the cicuit to prevent a fire. Arcs can be caused by drilling/cutting/nailing into a wire within a wall. Similar to a GFI, Ground Fault Interrupter.
I'm sure glad we installed that AFI, it kept the house from burning down.

Sellouts
AFI was a great punk band or "east bay hardcore," before they decided to turn EMO and make music for kids who like to cut themselves. I hope having your crappy new songs played on the radio was worth it AFI.

Get the AFI neck gaiter and mug.
A band that claims to be punk rock but in fact are just a group of flaming EMOtional homosexuals. In an attempt to claim they are not EMO, they just whine and and cry to the public that they are not emo... thusly making them EMO.
Important non emo person #1 AFI is emo
Important non emo person #2 Agreed

A Fire Inside
A really shitty scene band where the singer sounds like he's whining instead of actually singing.
My ears almost bled when AFI came on the radio for the 12th time that hour, so i put in a sublime cd instead.
