A drink served at the smoothie chain Robeks Juice. Although it is technically a "milkshake" the 800Ib gorilla is really just a whole tun of peanut butter mixed with protein powder. It has been described as both "delicious" as well as "repulsive." The drink is supposedly named because it contains 800 calories however it is common knowledge that it really depends on what size you buy.
