When a somehow large patty is placed on quite seemingly small buns and is oozing with big mac sauce onto your trousers
The other day i got a McClank and was driving home expecting a delicious snack to be soon consumed by my stomach. When out of nowhere the patty was protruding out the sides and leaking grease all over the wrapper. This continued to spread onto my trousers and create the worst stain of my life all do to this notorious McClank!
