Someone you fucked with before but don't have anything serious now.
Yo bro wassup with Brenda
Nothing she my old piece now.
An old object, e.g. a car, an instrument, a device, etc. which is still operational and reliable.
Jimmy's old reliable was his 1969 Ford Mustang, which he restored from his grandfather after gaining ownership of it.
Some one who is entirely way too old to be hanging out with teenagers. The middle aged guy that lives in your friends basement who you routinely employee to purchase you alcohol and as a "thank you" you let him hang around.
I can't believe Mark is still hanging out with those high school kids , what an Old Craig!
Finger a girl in the ass until she shits herself. Then lick your finger.
Casey: "Im gonna give that girl the old abend!"
An ex girl friend you still love, and still have somewhat of a relationship
"Even though Ashley, broke up with me, I still kick it with my old diamond."
Old men, over the age of any kind of logical use to society who insist on being in control. Usually insistent on being correct, and totally narcissistic in behavior. Often times asking someone's opinion on an issue, but quickly belittling them and criticizing the opinion as stupid or ridiculous right before they tell you the correct way. Never listens or considers anyone else but himself.
You can not win when up against old mantics (old man antics)
You know every single time he comes into the room we know we will be bombarded with "i told you so's", or "you should have's" - he's always up to Old Mantics
