Significality 

The belief that everything in the universe happens for a reason, one which may be unapparent, but present nonetheless.

If something happens to you, whether its bad or good, there was a reason behind it. Usually something bad is actually the start of something better, or the avoidance of something worse.

Signifiant

(Adjective): Trying to be daring and audacious in a big way.

Combination of 'significant' and 'defiant'.

"Cyclists blocked car traffic as part of their signifiant campaign to force the city to create more bike lanes."

"Dude, trying to chat up that hot girl you had no chance with was signifiant!"

sinical 

used to define the event of a poor mother who drinks red wine daily to have the feeling that she loves her only out of control daughter, and to cover up the fact that she's quite sad and doesn't know what to do

"her mother is so sinical, she's just finished her third glass of wine"
