Oh, FFS, you had best believe it; however.....for me, it's the inflection of the word dumbass that determines just how LARGE of a dumbass move I just pulled to warrant uttering the word.
For instance, I didn't bump my head on my car, not yet anyway; but this morning on my way out the door to physical therapy, ( had total knee replacement 3 weeks ago), I stepped down wrong with the cane I've graduated to from the grandpappy walker, and it hurt like a MF. That warranted a "duuuuuuuumbass", because it's a " I should have known" type of DA move.
Which, upon reflection probably account for damn near all mine anyway.
Carry on dumbass's of the world.
