blink at something
1. Lit. to open and close the eyelids quickly, one or more times. I blinked at the bright light and finally had to close my eyes. Don't blink at me while I am trying to take your picture.
2. Fig. to overlook something, such as a mistake. (As if one had blinked one's eyes rather than seeing the error.) I just can't blink at that kind of behavior. We can't blink at what evil you did.
