A term used to describe someone who was once sociable and self-assured but becomes shy, quiet, and reserved over time because of bullying, being excluded, or ostracized, especially for being different. It's like a flower bud that starts out open and full of life, but closes up because of tough situations, causing the person to hide their true self and lose their sparkle.
