Don Fucking Knotts is a term used when a person is fervent towards a material object.

Each word is enthused and usually shouted while the person thrusts the object towards the listeners face while each word is said.
"Dude, check out who's in this movie! DON FUCKING KNOTTS!!"

"Guess who I met yesterday. DON FUCKING KNOTTS!!"
