Grin-fucked 

In business when someone smiles and shakes your hand assuring you that they have heard and will act upon your recommendation or concerns when in truth you have already been ignored and dismissed.

Manager Bob: "Our associates will not repond positively to further cuts in their benefits. I strongly recommend against it."

Executive Dick: (Smiling, shaking Bob's hand and massaging his shoulder)"Thanks Bob, we'll take that under advisement. You know our employees are our most important asset."

Dick then processes Bob's pink slip and cuts non-management benefits by 30%.

Griffucker 

Someone who fucks the Griffin statue at William and Mary. The statue, a life-size bronze model of a griffin (half eagle, half lion), has a very prominent cock and balls, making it ideal for sex. This includes all forms of sexual activity, from ball fondling to handjobs to blowjobs to full-on vaginal or anal sex with the Griffin's metal cock. Some students put a condom on the Griffin's cock, while others prefer to take it raw, accepting any and all risks.

This term was coined by the campus satirical newspaper, the Botetourt Squat.

Katie: Hee hee hee guys, I rubbed the Griffin's balls last night, I guess I was a little drunk...
Leah: What do you mean, you rubbed his balls? You literally took his entire cock in your pussy!
Katie: Ha ha, either way, I'm a Griffucker!
