A "Soft Cock",

A person who who cannot consumate.
A very poor effort or attempt.

Derived from FINNISH words meaning exactly FLOPPY DICK / penus.
Example a sales guy makes the deal, but the factory screws up on the delivery.

Like flirting all night to get a lady into bed, then producing a flacid member, at the crucial moment.
