Knuckle Chum 

When you give yourself a hearty wank and bust a load all down your hand and fingers and fail to clean up the nut adequately leaving crusty jizz on the knuckles.

You might want to put a little hand lotion on your digits there braaaaaahhh. Skin looks a little dry and flakey. Naaaaaahhhh brooooohhhb that’s just knuckle chum. I didn’t wash my hand earlier after I gave it a good wank.
