To mark out/Marking out is another term for when your body/mind realises it’s made a promise to itself or another person that It realises it can no longer carry out. Aka to pussy out, to fanny out. Made famous by the ultimate pussy/fanny Mark Filby esq.
I’d of loved to join you in that healthy dose of cardio vascular activity but at the last minute I Mark’d out.
