fink out
Chicken out suddenly
To fink out is to back out of a commitment or lose nerve at a crucial moment: He was supposed to ask for a raise but finked out at the last second.
The phrase suggests weakness or cowardice—failing to follow through when courage is required.
Related to but distinct from the noun fink (an informer or contemptible person).
