In-group vs. Out-group (aggression)

Going to football games easily demonstrate in-group vs. out-group. When divisional rivalry go against each other, fans get crazy. When Raiders play against the Chargers at Qualcomm stadium, Chargers fans will form an alliance and the Raiders fans form an alliance. They will go against each other by trash talking and sometime fighting. This is also another example of hostile aggression. This clip pretty much explains everything.
