Flunker 

A good for nothin' waste of space that will never get into a university. Does nothing but smoke dope and play games all day. Never pays attention in class, and will never become anything useful in life.

Because Robert played games all day, he never went to university. His parents were ashamed of their son becoming such a flunker.

flunker fans 

When you spit on your penis then cumshot in a fan. You have to catch the cumshot in your mouth off the bank. If failed to do so you have to stick a toothpick down the mouth of your penis

Later tonight Ima play a game of flunker fans.

Junker Flunker

1. An old car that doesn't qualify for the $4,500 cash trade-in incentive from the government because it gets more than 15 mpg.
2. The sudden realization that your old beater vehicle is lost in the twilight zone between "generally worthless" and "totally worthless," forcing you to keep driving it for another year -- at least.

"I just looked up the mileage for my 1996 RAV4. The stupid Junker Flunker gets 16 mpg, which means I won't be getting any of that government cash after all. Drat!"

mother flunker 

A loophole swearword for "motherfucker".

She called her teacher a mother flunker, and almost got away with it.

stuperous funker 

An insult used by Mr. Burns in the simpsons. Probably his old way of saying "stupid fuck"

"Get out of here you stuperous funker!"
