A white knight is a guy that defends and protects girls for no reason.

Unlike regular knights who's acts are steeped in desire, a white knight truly desires nothing more than her well being, and would rather be somebody who really loves them and really cares for them, to harrowing inconvenience, in loss and to be that real, existing inside another heart in a way that can never end pathetically, generically and foolishly.
I white knight for girls. That's what I do.

an alcholic beverage consisting of jack daniels whiskey, and a favorite mexican beverage called "horchata", which is made of sweetened rice water and cinnamon. While at a birthday party for a friend, another friend and i were having trouble finding mixers for our jack daniels whiskey. we then came across the horchata and combined the two. henceforth it shall be known as thee "WHITE KNIGHT".

A White Knight is someone who goes on to the website Urban Dictionary and creates a definition under the name of their more than likely obese girlfriend. Type in almost any girl's name into the search bar and you will pull up one of these definitions.

Typically they will state what "a cool person they are", "how smart they are", "how cute they are", or other various statements about a girl no one but said White Knight gives a fuck about.

The only reason such definitions are even made are so they can show their girlfriend (obese) at how creative and cute they think they are being despite the fact 1000s of other dick bags have done the same thing already.

These definitions are quite annoying especially if you have the Urban Dictionary app for your Droid and constantly get them as a random definition.
Examples of douche bags being White Knights:

1. Kelly

The smartest person ever, someone with a great personality, has golden locks of hair.

2. Susan

The face of a tranny, hands of a man, junk in the trunk.
