Chemistry students finding a way to decline social invitations through chemical formulas is peak lab rat behavior. Sodium (Na) plus Bromate (BrO₃) gives you NaBrO₃, which sounds exactly like "Nah, bro" when read aloud. The perfect response when you'd rather titrate solutions than socialize. Some chemists say they have no reaction to jokes like this, but that's just because they're noble gases.
Nah Bro-mate
