Top Definition
When a woman nearly overdoses on testosterone, causing her clitoris to grow to the point of looking like a cheap Made in China version of a full-grown penis.
A: "I was watching women's fitness on TV yesterday and I'm pretty sure that one of those women had a penis."
B: "No, that was just a testosterone-enhanced clitoris, a 'testosteris'."
