Updated: 2026-04-24

## Definition

to suddenly stop helping someone or leave a situation when you are needed.

For teachers: to abandon a person, commitment, or responsibility, particularly at a critical moment or when the situation becomes difficult.

## Examples

- He promised to help me move, but he bailed out on me.
- The lead singer bailed out on the band just two days before their first big concert.
- Investors began to bail out on the startup once they realized the product would not meet its ambitious launch deadline.

## Pitfalls

- Not "He bailed out me." but "He bailed out on me." — the preposition 'on' is necessary to indicate the person who is being let down or abandoned.

## Usage notes

- Usually followed by a person or a specific project.
- Teaching tip: contrast with the financial 'bail out' (to rescue); here, the addition of 'on' shifts the meaning from 'saving someone' to 'abandoning someone'.
