A poor effort or something that just isnt up to scratch. poorly done and usually done by a dickheap. is completly irrelivant and bad. used against sketchy dudes who are under the influence of weed hence "bake"
person 1: "check out that Loserbake of a fish n tits shop"
person 2: "yer its really dirty and the was a greasy joint in the fryer, i heard the owner is a massive dickheap"
