A hobby that captures a persons interest for hours, days, weeks, or seasonly but is inevitably replaced by a new micro-hobby. A person may achieve a moderate level of competence, but due to their lack of attention and focus, never become and expert. Micro-hobbys routinely come and go as a person enters a different stage of their life, and quite often help deal with boredom, work life imbalance, and stress.
Whats your dad working on now?
Oh, he has this new micro-hobby. He's trying to build a robot in the basement. He will get bored of if by next week and move onto some hipster hydroponic water system.
A hobby you spend hardly any time on, but that you claim because you bought the gear.
Bottom says he’s taken up bodyboarding, but it’s just a vacation micro hobby.
