Man Smell is a cologne. It may cause fogging in Cybertronian optics.
Man Smell was Kade Burns' "signature scent". When Graham was having trouble attracting the attentions of Amy, Kade attempted to help by introducing Graham to his secret weapon: Man Smell, though it mostly induced coughing and irritation in everyone present. Boulder suggested that Kade should keep his secret weapon a secret. Graham failed in his subsequent attempt to attract Amy, despite the abundance of Man Smell, however he was later inspired to create his own cologne, dubbed "Confident Me".
