When an ex- boyfriend or girlfriend constantly stalks and tries to find out every new detail of their former significant others life. They try to gather info from mutual friends, facebook, drive bys, etc... As if writing all of this info on a big chalkboard.
I wish my ex would quit chalkboarding me. He needs to get a life and quit stalking. Its over.

Doing lines of coke off the back of the chick you are doing doggy style, and watching porn at the same time.
