Short for 'Open Ass Fart', To OAF is when you hold your butt cheeks open and fart. With your butt cheeks spread your butthole opens and makes a quiet wind noise but the deadly smell will consume the room.
'Omg look it's Jenny and her friends, they're always so mean to me'
'Why don't you go over and OAF at them? That'll teach them'
'You know what, why not!'

An acronym for 'Old as fuck' - Pronounced as spelled.
Used to describe an old person, also usually a luddite.
