The subtle act of pleasuring one's self (male members only) through inserting the tip into a door jamb, or other hinged objects, and then proceeding to slam said object aginst the tip thus making it bleed. This results in not only immense extreme pleasure, but also a lovely indoor fireworks display of man magma, a name derived from the appearance of blood stained jism.

To wank, or be wanked, in a particularly aggressive or over-enthusiastic manner. Usually involves an element of discomfort on the part of the person whose penis is being so manipulated.

Origins disputed, though commonly thought to stem from the mastubatory practices of Slovenian men, who, too used to driving tractors with rusty or stiff gear sticks, would manipulate their penises in a similarly vigorous fashion.

Nowadays if you are being wanked in such a fashion it is unlikely that the man wanking you is a genuine Slovenian tractor driver.
P: Bloody hell - he was pulling on my dick so hard it almost came off!

R: Oh - do you not enjoy a Slovenian Power Wank?
