Guinness shits

The diarrhea and/or flatulence caused by drinking a lot of Guinness. It usually doesn't come into effect until the morning after.

When ya drink a pint of the beauty elixir and spend your next 2 years on the toilet

Person 1: Have you seen Tommy? Haven’t heard from him in ages
Person 2: Oh Tommy? Oh man, he’s got the Guinness shits
Person 1: oh fuck rip him then
