A combination of the words "boyfriend" and "hand" - A social media (instagram) phenomenon where someone (usually a girl) continuously posts first-person photos of her legs/lap, her food while dining, her bed comforter, or other inanimate objects, always featuring a mysterious, unidentified hand, usually seated with her, on her thigh, or somewhere peripherally; outside of the subject of the photo. No one knows who the hand belongs to, because the person it belongs to is never tagged in the photo. Ever.
