Testacity 

Having the audacity to test you. (Starting a problem.)

How dare you have the testacity to talk to my girlfriend in front of me!?
I hate him so much! What testacity!
The testacity that was just seen was unbelievable.
Derek, don't come at me with your testacity!
The testacity! The testacity!

testentation 

1. Pretentious male-like display meant to impress others
2. boastful male-like showiness
3. male-like tendency to respond in a more serious manner than a situation calls for, particularly when one's aura of dominance is threatened.

Brian was too busy maintaining his testentation to enjoy the casual remark about his shoe size and it's correlation to something unidentified.

Testelistic 

Becoming ballistic, but your stones start to vibrate as you rampage.

I threw John's phone in the river yesterday and he went testelistic on me.
