Any person, male or female, in a film, book, game, stageplay etc that is acting in a pretentious, less than eroic manner, who ruins completely an otherwise good story.
Examples of a captain jirk are...

David from Shaun of the Dead
The Dolmen from Star Trek TOS Episode 'Elaan of Troyus'
Cypher from The Matrix
The Dursley's from Harry Potter series of books and films
Caligula from real life history and the film 'The Robe'
Brad from Superman 3
Belloq from Raiders of the Lost Ark

Etc.
