|1.||dog chew toy|
an act of showing one's testicles by pulling them up over one's boxers, shorts, etc. and leaving them there to hang and parade them around to people. Thus, with only the testicles showing, and the lack of blood flow to the scrotum, they actually look like a dog chew toy.
"i whipped out the dog chew toy on my sleeping roomate after slapping him in the face."
