The Angry Face should be one of your go to faces in the event of a scenario that requires anger. It’s the kind of face you would use if someone rudely and dangerously overtook you on the motorway. Therefore it’s a pretty powerful expression that should be used with caution whilst messaging amongst friends (unless of course the subject of the chat is something that requires mutual anger). In circumstances which incite an angry reaction, it’s perfectly acceptable to use the face by itself. And depending on the severity of the circumstance, a few expletives may not go amiss. Or you could opt for the Cursing Face in place of more colourful language.

Approved as part of Unicode 6.0 - Angry Face was added to Emoji 1.0 in 2015.
