The Germans really cooked making "Hobbyless behaviour" an insult. It is both devastating, applicable to a wide range of people and behaviours, and doesn't resort to swearing.
Man ranting on the internet about the Superbowl halftime show or complaining that something is "woke"? Hobbyless Behaviour. Girls mocking another girl for not looking right? Hobbyless Behaviour. Mindless vandalism? Hobbyless Behaviour.
It is more powerful than "get a life" or the English "You're Sad" because it gets to the central point of the matter, and that is wonderful. Danke, Deutsch.
