it basically means "what the fuck" but funnier since if you get cut mid-sentence, you have to start over, making it 2x funnier than it was before, because that's how broken my humor is.

"Boo Diddly Squat" is my second Sheryl Crow's "Soak Up The Sun" joke. "Boo Diddly," is a Super Mario Bros. series, ghost enemy. "Soak Up The Sun," mentions her job, "doesn't pay diddly squat," meaning it doesn't pay her enough. In this case, Sheryl Crow, in the Mario's Mushroom Kingdom, is angry, that Boo Diddly's doesn't get paid, for working for Koopa Bowser! A joke!
Sheryl Crow, is angry, that a Koopa Bowser minion, a ghost, is paid "Boo Diddly Squat" despite being, a great employee, of this boss! A joke!
