To describe speech or behavior that treats a serious topic with inappropriate humor or casualness, often offending others.
From the verb ふざける (to joke around). Used attributively to mean 'flippant' or 'messing around' in a negative sense.

Casual noun meaning 'joking around' or 'flippant behavior'. Often used for someone who constantly makes light of things.

To describe a remark or manner that is informal and light, sometimes inappropriately so, but not strongly disrespectful.

Means 'light-hearted' or 'without much thought'. Can be used for a flippant attitude that is not necessarily rude, just casual.
There is no single Japanese word that perfectly matches 'flippant'. Using a dictionary gloss like 不真面目 or 軽薄 without context may sound unnatural. Choose based on the specific nuance: disrespectful joking, lack of seriousness, or casual tone.
不真面目 focuses on lack of seriousness, often in duty-bound contexts. 軽薄 implies shallowness and frivolity, more about personality. For a flippant remark, 軽口 or ふざけた are better.
彼はいつも軽口を叩いている。
He is always making flippant remarks.
It was a flippant remark, but it caused a misunderstanding.
