put your money where your mouth is
Meaning
Back up what you say with real action, commitment, or financial support instead of just talking.
Origin
Recorded from the early 1900s in American English, the phrase uses money as a symbol of real commitment: prove your claims by staking something of value, not just talking.
Notes
