Acronym, stands for Post Work Eating Binge. A PWEB is the act of stuffing ones face with food immediately on returning from work. Usually this consists of left over pizza, curry or other last nights takeaway. If last night didn't involve takeaway, the foodstuffs can be toast, slabs of cheese, ham, or other tasty morsels found in the fridge and requiring no preparation.
