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.

afi stands for "a faggot inmybutthole". Their music can be compared to the sound of babies being devoured by lucifer, pigs being mass slaughtered, and emo kids crying as they cut themselves to sleep
Emo kid: dude i love afi
normal kid: dude, you think your life sucks? try being a vietnameese prostitute that gets raped every day and has to use coat hangers to perform abortions on herself. Then talk to me about your life
Emo kid: im to deep for you to understand! *runs away crying with eyeliner runing down face*

A girl who pops up when guys have stopped peeing in the urinal and sucks cock. She also molests horses and makes out with potatoes.
I advise you stay far far away from this girl.

Guy: OMG AFI'S SUCKING COCK!
