Bleeder

Bleeder is an informal term for a hemophiliac, a person suffering from hemophilia, a genetic disorder mostly inherited, that impairs the body's ability to make blood clot causing it difficult to stop bleeding. A person who bleeds easily is also called a bleeder. Bleeder is also the blood vessel that bleeds freely during surgery.

Bleeder is also a term in sports. It is a ground ball passing between two infielders in baseball.
