Fake-out on second turn

[Solonwise]

I was battling a wil meouth near Vermilion and in the first turn, it attack me with fake out. My pokemon flinched, and thats ok. In the second turn the meowth used fake out again and the attack, of course, failed, but the message "critical hit" appeared. It hit me with a critical hit, but at the same time, it failed.
