Random acts of Duncan. Everybody knows a dude named Duncan that is wildly unpredictable. A "Slam Dunk" is an action, or an opinion, that is not beneficial to society. Slam Dunks are usually ridiculed for being so out of place and detrimental to a good time (ie: parties, epic Facebook threads, and conversations), but have been known to produce laughs. In general, Slam Dunks are usually a bad thing.
In speech, "Slam Dunk" is usually used before or after the word "Bitch"

The male climbs atop a wardrobe or similar tall object, the female lies face down with her arse protuding in the air. The male then leaps off and attempts to engage his cock with the female arse. points can be obtained if the male actually achieves this. Extra bonus if he can smack the back of her head whilst landing.
