velcro

A Velcro person/velcro refers to someone who is overly clingy, needy, or dependent, often attaching themselves to others in a way that feels intrusive or suffocating. Just like the fastening mechanism of Velcro, they "stick" to people and situations, making it hard to create distance or have personal space. This term is often used metaphorically to describe someone who requires constant attention, companionship, or validation.

He's like velcro, always hanging around and never giving me any space.
