noun
twice divorced; two-time divorcee; two X marks (on family register)
Jocular slang referring to someone who has been divorced twice. The バツ (×) symbolizes a name struck from the family register; バツ２ means two such marks. Often used self-deprecatingly or humorously.
彼はバツ２だけど、まだ結婚に前向きだ。
He's been divorced twice, but he's still positive about marriage.
バツ２の芸能人が再婚した。
A celebrity who had been divorced twice got remarried.
From バツ (×, 'cross mark') + ２ (two). The × symbol is used in Japanese family registers to indicate a name that has been removed, often due to divorce. The term is slang and humorous, likening divorces to accumulating 'strikes'.
