Silvermask 

Silvermasking is a fraternity sex game played on girls by frat guys. One frat brother begins having sex with a girl in private. In the middle of intercourse, other frat brothers burst into the room wearing nothing but masks made of tinfoil and tinfoil covering their genitals. The silvermasked frat brothers dance around the copulating couple, typically having the effect of seriously freaking out the girl. The reaction of the frat brother who is engaged in intercourse could range from embarrassment, to anger, to unabashed hilarity -- mostly depending on whether he was expecting the prank or not. Silvermasking is purported to have been a common prank (maybe invented?) at the SAE fraternity at the University of Illinois in the mid-1990's.

"Hey, I hear you hooked up with that Chi-O hottie last night!"
"Yeah, but those senior bastards silvermasked me in the middle of it. I mean, it *was* really damn funny, but I am kind of pissed that the interrupted an ruined one of my most epic hook-ups ever."

Silvermark 

Silvermark is a silver streak of hair which is commonly found at front hairline (right or left-hand side where the forehead and hairline meet). A Silvermark can appear at a young age (as ealry as 7 years old) and its known to be hereditary - it is very likely that others in the family tree (genealogically speaking) proudly display the mark. There is a myth whereby some believe there is meaningful connection among all Silvermarks - a pedigree mark which can be traced back for centuries. This birthmark can be found in men, women, and children in each of the 194 independent countries around the world. A Silvermark on many occasions has been perceived to carry an air of mystery, charisma, and charm and in some countries for centuries, a silver streak of hair has been called a witch's streak.

Stacy London of "What Not to Wear" has the unique and “very distinguished” Silvermark and like most who have it, she's had hers since she was a child.

Silverman 

A male, usually timid and without a mind of his own. Who consistently has to deal with an abusive girlfriend or wife. This person usually has no idea that they are being abused and/or does not consider her behaviour to be abuse. Often times making excuses for her and doing whatever she commands. The girlfriend of a Silverman is often times controlling and restrictive in nearly all aspects of his life; especially when it comes to his friends. It is the duty of all good friends to make sure this kind of relationship ends permanently or doesn't begin at all, or else this cancerous girlfriend could ruin your friendship.

The word "Silverman" refers to the character Darren Silverman, played by Jason Biggs, in the movie Saving Silverman.

"Dude, Bini's turned Dom into a Silverman, she's such a fucking bitch. She won't even let him hang out with us."

"There goes Bini, bragging about the guys who want to fuck her and talking bad about Dom again...and he's okay with it. She's turned him into such a Silverman"

"I heard Dom finally broke up with Bini, good....He was such a Silverman in that relationship."

"Dom's been drinking a lot more lately. I heard Bini put him on the couch too. I don't ever want to be a Silverman like that guy."

"Friends don't let friends become a Silverman."
