When a male attempts to stuff a lot of napkins up his asshole for sexual pleasure. A form of masturbation. Old men tend to use this method more than younger men. Occasionally this method is overused and the asshole tends to stretch and rip, causing a bleeding asshole.
My grandpa tried the napkin testosterone boost last night. Now he went to the doctor and had to get surgery on his ass.
OHHH! yeah! my napkins helped my body fill up with pleasure last night!

A male affliction. The propensity to blurt out something better kept yourself when internet chatting to a woman you do not know very well.
He: You are really pretty, So what do you do?
She: I'm an accountant
He: Oh that's really impressive, I want to fuck the arse off you
She: and you are suffering Testosterone Tourettes Syndrome or TTS

When someone is either overly arrogant or aggressive regarding a topic where that attitude is completely unnecessary. People displaying this attribute will typically fight until the very end, even when what they’re arguing is clearly wrong. They’ll then try to fight you if you tell they’re stupid.
BS: We’re driving my parent’s car — don’t do ANYTHING that burns gas. Good thing the AC doesn’t use any gas.
Person 1: I’m pretty sure it does
BS: No
Person 1: really?
BS: the AC is powered by the alternator, which is powered by the battery of the car, not the engine.
Person 1: and the battery of the car is powered by the engine, which burns gas.
BS: do you want to fucking fight?
Person 1: now’s not the time for your Bullshit Testosterone
(BS then argued with a mechanic about this very topic for a half hour)

The gender- and sex-essentialist belief system which states that men are inherently more dominant, powerful, aggressive, or ambitious than women. Usually accompanied by the parallel belief that women are inherently more submissive, weak, nurturing, or delicate than men.
Man: I want to have kids, but I fear I won't be as nurturing to them as their mother.
Women: Don't let the Testosterone Rex get to you, sex doesn't determine how nurturing you are!
Women: Don't let the Testosterone Rex get to you, sex doesn't determine how nurturing you are!
