It can also be done unintentionally, such as when you sneeze really hard and manage to cover your mouth but it gets diverted to your nose, spraying particles every which way. Regardless it's pretty disgusting so make sure you use a damn tissue next time or if you don't have one sneeze into your sleeve.
