Back when getting high and spending hours buzzed out of my tits in a McDick's was heaven on earth- a buddy of ours invented the McTaco. So basically, he would get a Double Big Mac with extra Mac sauce and BBQ sauce.. He would open it right up, take one of the middle breads (with one patty and cheese slice inside and some of the onion/lettuce dust hanging around) fold it, and fill it with ketchup... then do the same with the other 1/4 bread, and another patty'n'stuff and fill it with Mac Sauce. and sometimes BBQ sauce.. SO-after eating those (head tilted) he'd be left with a normal, though slightly mutilated, regular Big Mac to round out the meal, and give him that pure Big Mac flavour. This never appealed to me, but the ability to crank up the calories so much always kind of impressed me.
