I don't think @1li intended this to be a joke, a "mob", unrelated to Arduino, a "shouting out" of their love, or cursing of a battery-pack. So I don't see how Bar Sport categorization would be appropriate.
It is true that some forum members select the Bar Sport category for topics that are related to Arduino and are not strictly a "joke" in cases where they want to encourage a light hearted and wandering discussion, and that is perfectly fine, but that is a decision for the topic creator to make.
