Arm Loot is classified as a "cackle" or group of individuals, typically female, that is required for entrance or acceptance to an event. It is defined as "loot" as opposed to candy because candy is retained by the owner whereas loot is meant to be shared. Although not restricted to the collegiate lifestyle, arm loot is most often required for events where attractiveness is key and the ability to flip a quarter into a cup will garner praise from fellow party-goers. Under certain circumstances, the qualifications for loot could necessitate a trade-off between attractiveness and a certain morally casual attitude.
