Has to do with the masculinity of a woman either physically or mentally.
Physically- The woman has heavy characteristics like she is taking steroids resulting in hairy chest, deep voice, and muscles bigger than a guy can handle.
mentally- Extreme feminist who makes the man spineless often spotted when the man stays at home and watches the children or takes her last name in marriage.
Guy 2, yeah, but i miss her.
Guy 1, Damn your spineless that girl has bigger titesticles than i thought.
