the social act of peer-pressuring someone (a 'douchebag', the term from which 'bag'-rolling originates) with low self esteem into throwing themselves down a hill. This usually results in moderate injury to the victim, for the entertainment of their peers. Usually occurs in an outdoor environment, although bag-rolling has been known to occur on indoor ski-slopes and downwards escalators, amongst others. the victim partakes in the hope that their own social status will be increased, although in most cases they are turned into a source of open mockery.
