cock knocker

A Cock Knocker is an individual who frequently masterbates men. Calling a man a Cock Knocker is like calling him a homosexual. Calling a woman a Cock Knocker is like calling her a loose whore who touches men frequently

Nelson is a Cock Knocker, therefore, he masterbates other men and is a homosexual.
