coo-coo

Soft bird call

Coo-coo is a variant spelling of cuckoo, usually in its informal sense of crazy or foolish: That idea is coo-coo.

The spelling emphasizes the bird's call—the source of the association with madness, since cuckoo clocks announce the hour with repetitive, slightly manic sounds.

Also appears in coo-coo for Cocoa Puffs, meaning wildly enthusiastic.
