Angryphone means: An English-speaking resident of Quebec who demonstrates systematic anger or aggression towards the French language or against the actions of Quebecois nationalists, or who is a peevish complainer.. It is mainly Canadian English and may not be understood outside that context. There is no real cause for parental concern; it is descriptive vocabulary rather than risky behaviour. If your teen uses it, context will usually make the intent clear. A short, curious question about where they heard it is usually all that is needed to know whether to follow up.
