a type of cockblocker
(noun, verb: White Knight. adjective: White Knightey.)

a male acquaintance of a woman who, usually motivated by jealousy, attempts to cockblock the woman by defending her (implicitly, her chastity) from another man.

Though the White Knight typically attempts to persuade the other man that the woman is "not interested," the White Knight usually is motivated to act in the first place only because he senses that the woman is attracted to the other man.

Amongst cockblockers, the White Knight is a relatively impotent type, because (i) the woman usually knows intuitively that the White Knight wants her and is motivated by his jealously, and (ii) White Knights almost always have low to moderate social skills/influence (which is why they are White Knights, because they do not get laid themselves), so the woman also knows that the White Knight's irritation is not likely to have negative social consequences for her. However, the White Knight's attempts are sometimes successful, often only because he unwittingly embodies the woman's fear of Slut Shaming (being judged), a very potent cockblocking force.

Typically, a man who behaves as a White Knight is in a pathetic state of mind. He feels for some reason that he cannot get laid, so reduces himself to trolling other men, especially men who happen to be hitting it off with women whom the White Knight has a history of fantasizing for.
