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.
