It's no secret that men go into 'Macho man' mode to impress a girl. Slacker is the guy that fakes interest in a girls hobbies in order to have more in common with her. One time, he was with a girl that was really into mountain biking. Thinking 'I know how to ride a bike' he went biking with her and it didn't end well for him and his man parts!
What's the dumb stuff your man has done while trying to act macho??
