Combination of wank and angst, sometimes spelled as wankst-

Ridiculously overblown self-pity.

A phrase to describe someone who is cognitively degenerating. Synonym of "going off the deep end". Can have varying degrees of severity.

Reference to the song "Hey You" by Pink Floyd. The line "and the worms ate into his brain" makes no sense in an otherwise linear and literal narration throughout the lyrics.

Metaphorically wanking over your angst. Throwing a pity party for one, over something that isn't necessarily worth a full blown pity party. Overthinking things, creating teen emo art, but looking back at it and having a laugh about how wangsty you were.

Wangst often results in bad poems, black and white selfies by windows with rain drops on them, or other tumblr-esque art.

It is true that most great artists have gone through times of wangst, and emotional turmoil.

Most often found in bad fiction (especially fanfiction), wangst is the combination of "wang" and "angst"; it's a condition where a character is supposedly unfortunate and deserving of pity but the real emotion the viewer/reader is supposed to feel is awe at the character's awesome power and l33t sk1llz.

A good writer can write a believable character who has a lot of power but whose life still sucks. A really good writer can even write a believable character whose life sucks as a direct result of having such power. But when bad writers try to combine these two things, the result is often wangst.

The deep shameful feeling a man experiences in the aftermath of masturbation. It is unclear whether women are known sufferers but there are certainly cases. A combination of "wank" and "angst" perfectly conveys this inexplicable emotion. It is overwhelming and often leads to a vow to cut down on masturbation, although this never lasts.

Purposefully exaggerating angst to garner sympathy.

The angst and in-fighting among a group of friends, blogging community, etc., resulting from one or more acts of wankery.
