when someone drinks milk very quickly on the day of the expiration date
Person a: what happened to that gallon of milk in the refrigerator?

Person b: Oh, I gave it an expiration chug, so it wouldn't go bad.

Person a: Good thinking!

when someone goes to the refrigerator, chugs the last bit of milk only to realize the milk has expired...
Phill raced his younger brother to the fridge so he could chug the last bit of milk...only to realize it was expired and sour... his younger brother said dude i am glad you took the expired chug and not me.
