best friend
Your trusted ally
A best friend is the person you feel closest to among all your friends—the one you confide in, rely on, and prioritize.
The relationship implies mutual trust and deep familiarity: She's been my best friend since third grade.
Children use the term earnestly; adults sometimes ironically: Chocolate is my best friend right now.
The abbreviation BFF (best friends forever) emphasizes permanence.
