go bonkers

Completely lose composure

Go bonkers is to lose one's composure or sanity, either literally or through extreme excitement or anger.

Someone might go bonkers waiting in a long line, or go bonkers over a new puppy.

The phrase suggests a dramatic, often comic loss of control rather than genuine mental breakdown.
