flanksteak

I a very bitchy person who gives themsleves away to the opposite sex too easily. They also do stupid or demorralizing things and then get angry when people talk about them behind their backs.

Give me an example of a flanksteak and I will give you a dollar.

flantastic

If something is Flantastic it is extremely jewish, sticky, and dirty. A flantastic item would be something like a used uncleaned double-dong and doing a flanstastic deed would be like giving yourself or another person the reverse shocker.

If someone is called flantastic it means they are easy, slutty, and/or dirty.

Dude that bitch was so flantastic in bed! She let me use her any way I wanted!!

flintstoning

Being in the middle of a task at work and just dropping it and leaving the minute your shift ends.

(In the first 10 seconds of the Flintstones intro, Fred is busy lifting a rock out of the quarry, but as soon as the whistle blows he's out of the quarry and into the car)

"Never give him a task that takes more than 15 minutes at 4:45, because he'll be flintstoning on out of here at 5:00."
