Used by idiots who can't articulate correctly in place of the word "have".

Cross-reference: Often used in the same sentence as "your" when what they really mean to say is "you're".

In frequent use in England.

I came up with this in the late 70's. An O.F. is an occasional fuck. Someone you have no real interest in because every time they opened their mouth nothing but stupid came out. But they were gorgeous, good in bed, but absolutely not to be seen in public with.
Please do not tell me that I saw you with him at the Elbow Room last night. I know that you were snot slinging drunk, but he's your fucking O.F. for Christ's sake!

old fashioned, or commonly known as Old Fuck. This bastard is only 18, but acts like he is 85. He will tell you war stories and have no idea what the fuck he is talking a bout because the only action he has seen is in the great squirrel massacre of Plymouth Rock. When you come to visit him you will be greeted by what at first looks like a old man that has see his far share of shit, but no its a 18 year old in a pair of overalls chewing on a grain stock, rocking in a chair with a 12- gauge shotgun in his lap. Oh, what is that you hear? It's fucking old time country music, and we're not talking about Johnny Cash, we mean some real red neck I fucked my sister type shit. If you are sensitive person don't come around because he is just as ruthless as he is old, or so he likes to think. The last thing is that he can't eat his food warm. He enjoys his nourishment to be between room temperature and -30 degree F.
O.F.: man I remember back with this all used to be farm land
George: Shut the fuck up OF, your baby ass hasn't even hit puberty.

Mom: Eat your food while its hot.
Son: I like it cold
Mom: Wow you are so OF

O.F.: A squirrel, only if i hd my 12 gauge
