From Denis Leary’s 1997 comedic routine/record/video Lock ‘N Load. Lexicon. Re-worked from the original (“You took the donut, you dunked it in coffee. Thus the fucking title of the place!”), as he explains why Dunkin Donuts is called that.

Used when it can explain a tautology:

“Turns out Hal’s Tavern is owned by a guy named Hal.”
”Hence the fucking name.”

(YouTube isn’t letting me embed any of the many videos with his Lock ‘N Load “Coffee” segment. Hence the fucking link. [see?] Not sure why the curly quote algorithm is broken in that line above, but I’m out of spoons for what I thought would be a quick entry.)
