A tradition where, upon a young lad’s awkward yet triumphant first solo adventure, his parents—presumably both proud and horrified—present him with a ceremonial piece of shortbread to mark his transition into a deeply confusing stage of life.
In the north of England this shortbread is often accompanied by some of the fathers custard.
Father : Here you go son, have a munch on this wankers shortbread.
Son: thanks dad I really love it
