When a person thinks like a "guy," but is not a guy. The "spread your seed" mentality and way of life that is usually unconventional, or even unacceptable. Usually an adopted lifestyle by a young woman.
"Like, omg, Paris Hilton has total penis mentality, she's dated everyone, not that she cares to remember them. Just another notch on her..."
