hack-tow rule of half
a sacred pact where you and your best mate take whatever food or drink is there and split it exactly in half, even if it means you end up with the worst part and your friend gets the best
We split the last burger and I got the lettuce and he got the meat
We split the last pizza and I got the crust and he got the toppings
We split the last drink and I had to drink the dregs and he had the nice part
