a hunkum is a special dance that is peformed by awesome gingers and occasional brunettes (if they are lucky)

they do not tell anyone of this secret ginger tradition, it is based on the worship of the love between rupert grint and rosemary gibson it is awesome
how it is peformed
you wiggle your eyebrows
you twerk
you tie a tie
you find someone called lucy
you eat quality streets
and you enjoy

A polite term for shoving a lubricated probe into the Earth's hole to release gas.
