fully fledged member of the international guild of fucktards

When someone is a complete and utter useless cunt, and is actually a lot more retarded than you previously give them credit for.
A very common attribute with new scaffolding labourers. They may be ripped to fuck and constantly remind you how they can lift 250kg in the gym but can’t pick up a bucket of fittings or more than one tube. If you asked one of these individuals to go to the lorry and get you a tape as you need to measure something they would most definitely return with duct tape.
