A fat teenager that makes up a lot of nonsense. Usually lives in a council house and loves traction engines. A wilko's breath normally smells like rotten garbage.
'That fat kid that loves traction engines is such a wilko'
'Hey, that kid's breath stinks and he lives on Queen Street, he must be a wilko!'
