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"
Dude 1: "We had this post on our Facebook group. It had a thousand comments on it, but Duncan deleted it"
Dude 2: "What!? Why'd you do it, man?"
Duncan: "It was my post bitch... Slam Dunk!"

Dude 1: "Did Duncan just walk through the drive-thru?"
Dude 2: "Yes sir... Slam Dunk"

Dude 1: "Hey Duncan, How was Spring Break?"
Duncan: "Well, I don't remember half of it, so.... Slam Dunk, bitch"
