Having the balls to sag more than most people with and having a gait that complement the walk and the talk. It's similar to up tight like an asshole but also the complete opposite while promoting an aura of freedom. Also can be spelled sagasscity and is pronounced sag-ass-sit-E

The closest antonym is conservative if you mix it with wedgy. But sagacity also hints at bravery and having the balls and/or guts to be yourself and stand out.
You can can see his sagacity is evident by his having the balls to sag more than the average person.

How saggy one's tits are.
This can be judged on a scale of 1 to 10.
#1 Mrs Mackereth's sagacity is off the charts!
#2 The topless sunbather's sagacity was a sight to behold!
#3 Her sagacity is only a 1. What perky breasts she has!

The belief the continuous pursuit of truth outweighs the comfort of faith. ‘Sagacism’ is derived from the word ‘Saga’ or ‘Sagacious’ meaning ‘wise’ or ‘having wisdom.’
The new universal term for Atheism, Agnosticism, and the Skeptically Faithful is Sagacism.
