A clapsacker is a word invented by my wife. Who likes to make up random words. The definition is someone who does everything exactly by the book, to the point of taking all the fun out of things in life. It originated when I told her, that she shouldn't plug her phone into the car when it wasn't running because it would drain the battery. She said, WTF, why do you always have to be such a clapsacker.

A man who messes around with other men, but no one would ever know by looking or talking to him. Used by gay black men to identify masculine gay men or DL Brothas.
