Say you have just had a liquid lunch and you’re on your way to that important meeting. Hopefully you’re on a bike, because you probably shouldn’t be driving. Though that’s another story. Wouldn’t it be great if you had some way of gauging whether your breath was capable of instantly pickling those who get to close to you?

That’s where the Etiquette Checker comes in. It’s a breathalyser that will let you know just how tanked you are. Simply breathe into it to get a readout of just how horrible your breath is on a scale from 1 to 6. The very fact that you need the Etiquette Checker should probably tell you that you have a drinking problem, but again that’s another story. At least you’ll have an edge and be able to take care of that breath. Hopefully you’ll put your best face forward and be able to hide the fact that you’ve been drinking girlly drinks.

Check out a video of unsuspecting Japanese guys using this to find out how tanked they are.
