This is how some little boys have to learn. Act cocky and try to fight with a guy who's much bigger and older than you . . . . . and eat the consequence. White Shirt got his clock cleaned.
16 year old boys think that if they're in a pack, that they're invincible. 3 scrawny teens against 2 big men is not a balanced fight - as they learned.
Fighting in Denny's.

Not always the case though, although that outcome happens more often. I know some smalls guys that would destroy both them big dudes.
