To put it simply, A Goodman is to destroy an object beyond any recognition. To so badly own and harmfully crush resistance to the point that the victim's own mother would not recognize him/her. The person who commits a Goodman is entitled to unbridled respect, shock, and awe, because of their prowess in all walks of life.
"DUDE....THOSE NUKES TOTALLY PULLED A GOODMAN ON NAGASAKI AND HIROSHIMA".
"Yo...Man... Kimbo Slice is the master of pulling a Goodman".
"Hey, did you hear? Jim's dog got hit by a tractor-trailer, then run over by a 16-wheeler, and crushed under a collapsing bridge...man. it suffered through one hell of a Goodman"
