Have you been dying to tell someone that their nose hairs gross you out? Do you find yourself facing them every day, unable to voice out your disgust? If your answer to these two questions is “yes” , Chololi is just the service for you. It allows anyone to email people anonymously, telling them that their pesky nostril hairs need to be trimmed soon.

Originally launched in Japanese, the web service is now available for the English-speaking as well. To use it, all you need to do is go to their website and fill out a form. Provide the person’s name, e-mail address, the nostril through which the hair is visible, the number of hairs and you’re done! The message will be conveyed in secrecy. Just for kicks, you can even choose the tone with which the message is delivered. There’s mild, strong, commanding, and the nastiest of them all, scornful.

Chololi does come with its own set of warnings. The websites advises users not to use the service against people who can’t take a joke, or those who really don’t have any nostril hairs hanging out. I know a bunch of people I could send this to. How about you?
