Orignial slag. You say "99+" in an IM when you are bored, have nothing else to say or just want cheep laughs. Sometimes used when there is an awkward situation to break the silence. Or just when the conversation had gone 'stale'. Always used on some sort of IM.
"I have somthing to tell you, I had sex with your mother..."

Used in reference to homosexual sex. A play on the usually heterosexual 69 position, where the numerals represent the position of the sexual partners.

In England '99' chiefly is associated with a popular type of ice-cream sold by ice-cream vans that are usually seen in seaside resorts.
"I went up to the ice-cream man and asked him for a 99. He gave me a large creamy one."

Putting your age as 99 on Myspace so that people can't troll you by your real age and spam you or send you stupid messages like "whazzup?"
I had my real age on Myspace but I got too many douchebags trying to hit me up, so I 99'd myself.

99

A NY coined term that originated in the 60's. Popular among Italians and the mainstream during the 60's,70's and 80's. A person that gets 99% of what you have to offer with the exception of love and genuine affection. Used to describe a loveless,superficial,sexual relationship where both people benefit in some way but where love and emotions are not allowed. 99 exchanges mock relationships in appearance but are a verbal agreement between 2 people to meet each others needs without emotions or stress. Usually short term and based on physical attraction,sexual compatibility and the ability to meet the other's needs. More than a sex buddy but far less than a long term relationship.
"I was gonna 99 that chick, but she'd be in it for the cheese and my pockets aren't built like that right now."
"Word,I copped a FLY lil 99,son! And all she want is the D. It's perfect!"
"I need a female to kick it with this summer but I don't need the stress,I'ma get out here and 99 a bad one watch!"
