What is Jon-a-thug?
A derogatory term usually given to white men over the age of 18. This category of fine gentlemen have at least one facial hair oddity, have a slight relgious tendency, stalk anyone that interests him, try to conform by following everyone around, watch pornography in plain view of others, injure themselves regularly in circumstances that ordinary people would not, and dismiss all advice that could be helpful to his unfortunate social situation.
"Mic Jagger is being such a Jon-A-Thug today." (secretly Mic is standing outside of the room listening to every word that is being said.)
