Scooby Doo Sandwich
A sandwich with so much meat, cheese, and other various fillings that it is literally so big that it looks like one of the towering sandwiches Scooby and Shaggy would always eat on Scooby Doo.
Person 1: Dude so I went to the local deli and I got a Scooby Doo Sandwich for only $5.
Person 2: That totally beats subway.
