“ONB” is an abbreviation that typically means “Outward No Bounce” in banking, referring to a successful transaction. In texting or social media, it can also mean “On Bro” or “On God No Bounce,” used to emphasize honesty or truth in a statement.

The abbreviation ONB among the slang ones mainly stands for "On Bro," which is a way to stress the truthfulness, honesty or gravity of a situation, in other words, like saying "I swear" or "for real". However, it depends on the context in which it is used, as in the case of the names of organizations like Old National Bank or concepts in the area of linear algebra.
