A condom that won't stay skin tight against a turgid male phalus due to a lack of penile girth. In the case of a droopy sock, penile length is meaningless and the condom sags down the shaft like an old sock with the elastic worn out.
While Carl was blessed with inches, he was not blessed with girth. His pencil dick was unable to support condom use as it always turned into a droopy sock.
