Books which would contain a person or teacher topic of some sort and was passed around where other students would write mean or harshful comments about them. In other words, "slamming" them, hence the term. They came around the 1940's and have since been forgotten and are mainly nationally banned. Virtual slam books are publicised on the internet where a question will be asked and the original "book" will be returned to the author, filled in.

The origin of the name can be:
To slam students, or other faculty.
Or the book was slammed when the teacher was near.

A girl lays down on a bed and spreads her legs while the guy backs up as far as he can. He then proceeds to run towards the bed and dive like superman "into" the girl( 50 points if you can pull this off running from a hallway). You end up slamming into her, that is where the slam part comes from. A friend of mine in miami came up with this when i was living there and told me about it. This is an incredible move for guys and girls if you can get your distance, arc, and timing right, but if you don't you can really injure yourself. Proceed With Caution.
(Also Known As A Leap Of Faith)

the act by which a person ejaculates on their hand and proceeds to slams the contents onto the victims face, and hold for no less than 3 seconds. This act may or may not result in the victim falling down in dismay. Not to be mistaken for cum slap

Origin: Shanking a bitch which you do when she has gotten overly emotional, socially awkward and sketchy on account of overanalyzing a semi-romantic situation involving a member of the opposite sex (i.e. man). Hence, "Shankavitch"; derived from German root words "Shonkol," to soundly destroy, and "Vitchen," a woman's every dream for a relationship.

When SVitch finds a girl in a vulnerable condition due to a questionable interaction with a guy, she senses her opening and begins to sniff around looking to make trouble or destroy the relationship at hand.

Legend tells us, she bears a striking resemblance to that longhaired dead bitch that crawls on the floor featured in many Japanese horrors movies, including "Ringu" and "The Grudge" (I don't know the word for "grudge" in Japanese).

Shankavitch oftentimes leads girls to such extreme manifestations of crazy-bitchness A) Facebook stalking a guy she went/made out with once B) Freaking the shit out of a guy by picking names out for their would-be children on their first date C) Screwing up a tim tam slam and consequently spilling about 8 oz. of hot tea into her lap D) Crying hysterically because her random hook-up, with whom she thought she "really had a connection" never called her back E) Whilst drunk, she has a heart-to-heart with a member of the opposite sex professing her intense interest in him, whom she only met the day before F) Making out with an innocent guy who she has no interest in, just to make another guy...
