How it's used

This idiom vividly describes a sudden and complete betrayal where someone discards their loyalty as easily as flipping a pig's stomach to reveal waste. It is specifically used to criticize people who become vindictive or ungrateful the moment a conflict arises or their personal interests are no longer served. The imagery is intentionally crude and harsh, emphasizing the total loss of respect between the parties involved.

Examples

They were so close before, who knew they would turn on each other so quickly.
The scariest thing in business is meeting people who turn hostile the moment things go wrong.

Common phrases

Common mistake

Do not use this phrase in formal or professional settings, as the reference to animal waste makes it quite vulgar and aggressive. It is strictly reserved for venting frustration about personal betrayals among friends or business partners.
