B$NG.
A Khmer phrase that means 'Will you marry me?' but also sounds like a curse when your ex uses it.
"He texted me 'B$NG.' and I thought he was asking for a divorce."
"My mom said 'B$NG.' and I realized she was proposing to my dad."
"I asked my crush 'B$NG.' and he just stared at me like I had 1000 bad breaths."
