A "pinky promise" is a symbolic gesture made between two people, typically children or close friends, to signify a sincere and unbreakable agreement or commitment. When you pinky promise someone, you interlock your pinky fingers with theirs, and it's considered a special and binding gesture.
In the context of promising something to a guy, it holds the same meaning as with anyone else. By pinky promising, you are expressing a strong sense of trust, loyalty, and honesty in your commitment to whatever was promised. It could be a promise to keep a secret, to be there for each other, or to fulfill a specific task or favor.
The idea behind a pinky promise is that it's a more solemn and heartfelt assurance than a regular promise. Breaking a pinky promise is often seen as a significant breach of trust, so it's essential to take it seriously and only make promises you intend to keep.
While the tradition of pinky promising is often associated with children, the gesture can also be used playfully or affectionately among friends of any age. It's a sweet and endearing way to show that you value and trust the person you're making the promise with.
