I had DIDDLY SQUAT to do with selling all that gay pornography to those terrorists!

You know diddly squat about anything.

I never did see so many of them all doing diddly squat at once.

Those shiny cars won't mean diddly squat when you die.

As I slit my wrists, I cannot imagine the diddly squat that lay at the end of the dark tunnel that is my life.

Oh man I just diddly squatted in the woods

when you father was an engineering student, and you are in a private high school and playing guitar in the music band, if you are not a talented a carrot in god's potato field, you have done diddly-squat with your private education.
