Testicular Fortitude 

A more academic English translation of the Spanish word "cojones", that originally stood for testicles, two spheric glands part of the reproductive system of males, also commonly known as balls.

To have testicular fortitude is to show strength, courage and sagacity in challenging situations. The story of how strength and courage is related to two nuts encased in shriveled skin hanging from between a man’s legs is a fascinating story that i don't have the time to go into right now.

You can’t win with reserve and lassitude
And you can’t face the unforgiving multitude
Without the manly trait of testicular fortitude

Texticular Fortitude 

Noun. The sudden boost in confidence one receives when communicating by means of text. Often visible when communicating through instant messaging or texting, when someone says something you know they would never have the confidence to say in person.

Timid Asian Boy: I hate you! You're a slut! I never want to see you again!

Burly Russian Girl: Say that to my face, Dickslam!

Notice the sudden surge of confidence in the Timid Asian Boy. He would never speak so angrily towards the Burly Russian Girl in person. He is experiencing Texticular Fortitude.
