Get the stfu mug.Acronym of "Shut The Fuck Up", also known as something you should say to anyone that has an opinion or in case you are tired of people arguing over bullshit. It's also something you should do if you just don't like something. Science approves that shutting the fuck up for who has an opinion is the best thing you can ever do!
