What does “Throw someone under the bus” mean?
Throw someone under the bus means to blame or betray someone to protect yourself or get an advantage.
Someone who throws you under the bus lets you take the blame or suffer so they can protect themselves. The phrase suggests disloyalty, not just an honest disagreement.

When do people say it?
Use it critically when someone shifts blame onto a colleague, friend or ally for their own benefit.

Is it formal or informal?
Register: informal. It is most at home in everyday conversation rather than formal writing. Most common in UK and US.
Where does it come from?

Origin confidence: Disputed; treat with caution
