A girl who acts more like a guy then she does a girl.When hanging with the guys, shes one of the dudes, not a dudet. Normaly engangeing in the manly man activities aswell. The name Sam is shortend from Samantha. Hence helping with her boyish attitude.
Dude A: "Dude, look at her, shes just like the guys!"
Dude B: "Nope, shes just Sam."
