The "bus" question

The word "bus" is a great Swedish word that unfortunately has no good counterpart in English.

It is pronounced "boos" as in tooth.

It is like a combination of when a child does something silly, funny, mischievous, and playful.

It is a great word to use when referring to things that Esther does. "Idag hittade Esther på mycket bus" would be something like "today Esther did a lot of things that were fun/silly/playful/mischievous", a little bit like Dennis the Menace but not to that extent.

Used as an adjective it is "busig", "boosig".
