Bin lid

An extra-large, round, flat bread-roll cut horizontally to make a sandwich, within which most often is served the Full English Breakfast. Full title might be "dustbin lid," named after the dustbin refuse receptacle of around 90 litres that predates the wheeliebin era. The lids are round and 50cm across, (20'' in old-money), the breads they're named after not as large, more like face-sized, but so called for exaggerated comical effect.

Morning, can I have a bin lid to pick up at 7, well done black pudding, tomatoes, no beans and a milky tea, one sugar.

Yellow Bin Lid Day

Taking out the plastics, removing the rubber.
Not wearing a condom.

“Yeah, on me way home for yellow bin lid day!”

“Silly me, wrong week for yellow bin lid day, and it was full!”
