The guy you don't know. You don't know why he's talking to these girls, why he's in the pictures or why he's even in the building. He's "trying" and the only thing he is doing is blocking and distracting attention from you and your people. Chances are you see a spare guy every weekend. You just didn't know the definition.
Your meeting some girls at the club and they bring along their 1 guy friend. Hes hasn't been able to seal the deal and is now in the friend zone. When you meet the girls he is throwing salt in your game and wont let you get any of them alone because he cant do it himself. This is a spare guy.
