goo-goo
Lovestruck eye descriptor
Goo-goo imitates the babbling sounds of infants, used when addressing or mimicking babies: Who's a cute little baby? Goo-goo!
The reduplicated syllables suggest preverbal vocalization.
Goo-goo eyes are exaggeratedly adoring or sentimental looks: He was making goo-goo eyes at her across the room.
