Testosterone Truck 

A “Testosterone Truck” (almost always driven by a man) is any large truck that is driving aggressively and always rides your car’s butt when you’re driving. Even if you’re driving faster than the speed limit, the “Testosterone Truck” must always ride your bumper or pass aggressively.

“Julie was getting fed up with the many ‘Testosterone Trucks’ on the road that ALWAYS seem ride her bumper as if to intimidate, as they bear down on her car with their huge front end and bright lights”.

Bull Shark Testosterone 

Bull Shark Testosterone or "BST" is overpowered shit in Grand Theft Auto Online used mainly by people who are shit at the game. It gives you double damage and health for 60 seconds. It also makes basically every weapon in the game 1-2 shot kill. Literally the best idea Rockstar has come up with.

GTA Online Player #1: "Dude I shot this guy like 25 times and he kills me one shot. WTF?!"

GTA Online Player #2: "He is using Bull Shark Testosterone dumbass."

GTA Online Player #1: "FUCK!"

Testosterone Boner 

Usually occurs from a man or boy between the months of May all the way to September. A testosterone boner is when a man notices a very attractive girl wearing minimal clothing and all the "alerts" of a boner go off minus the inconvenient and obvious side effect.

"Dude, G Thom, did you see that fine girl in the short shorts?"
"Hell yeah I did, damn girl gave me a testosterone boner."
"but you're not showing?"
"exactly, doesn't mean I'm not poppin' on the inside."
