Hey Shitty
The activation phrase that can and should be used to start an iOS Siri command.
While other funny phrases can't be used, phrases close to "Hey Siri" can be. So when activating that feature, I picked "Hey Shitty". So now I can say "Hey Shitty, start a timer for 10 minutes" which is funny, productive, and an accurate name all at the same time.
