talk a big game

Brag without proof

To talk a big game is to boast or make impressive claims, especially about what you can do, often without the ability or intention to back them up: He talks a big game about his connections, but I've never seen him deliver.

The phrase implies skepticism—someone who talks a big game may not perform when it counts.
