When a group of people persuades an individual to do something very immoral like painting his pants with an extremely odd pattern, run into a crowd of black people and jews and scream "SIEG HEIL" and so on.
The group often laughs at the individual when he or she does these immoral things. Group pressure can be an awesome way of killing time.
Mike and Dan convinced Daniel that its awesome to put 10 different hairgels of very poor quality in the hair. Daniel did this and Mike and Dan hade a good laugh!
