Rackan means: A chain or bar drilled with holes to accommodate pot-hooks from which cooking vessels can be suspended over a fire; a pot-hook.. It is a dialectal or regional word and rarely appears in mainstream teen culture; usage usually points to a family, regional, or literary source rather than peer slang. There is no real cause for parental concern; it is descriptive vocabulary rather than risky behaviour. This is a food-related word and harmless in itself.
