A serious medical condition that results in a man acting like a huge pussy. Low t symptoms include choosing to watch a movie with your girlfriend instead of drinking with your friends, ordering salads and specialty coffees, and generally paying too much attention to your physical appearance.
I realized Mike had low t the day he told me he couldn't come over to watch football because he had to go to cooking class.
You traded in your Durango for a Prius? The t doesn't get any lower than that buddy.
