That feeling "when the world seems to shine like you've had too much wine"

AMORE

Think of the Italian word that means love and rhymes with a famous pizza topping.

This clue quotes the famous Dean Martin song "That’s Amore", where the lyrics describe love as making everything feel bright and dreamy—like having too much wine. The phrase is a playful way to hint at the Italian word for "love," which is the answer. If you recognize the song, the connection to amore becomes obvious.
