when your friends are sick and tired of you punching them with a left hook to the liver...and excuse yourself by saying they were open for the shot.
When I hit my friends when they are open. My friends cover up or flinch when I make a motion to move my hand not even intending to punch them. Practice styles in any mirror. Associate big fights with Vegas or MSG
When you tap-jab your missus and give her a straight right when she's trying to hand you the TV remote.
you know you too much into boxing when your constantly checking on the site and posting when you should be studying for finals.
