The stinky smegma that gathers on the cheese ridge of an unhygeinic cock. Pronounced 'he-dam', the word is a splicing of 'he' and that crappy wax coated Dutch cheese 'Edam'. aka dick cheese
He had enough hedam on his todger to spread on a whole packet of cream crackers, but he though that would be a waste.
