It was quite obviously just an expression, I don't actually think you never leave the house. Then google what women's hands look like because you clearly have some weird misconceptions about that body part. Women's hands aren't much different from men's hands. They're smaller and less boney but still they are built in the same way. Women have veins, bones and their skin wrinkles as well you know? Those long fingers, perfectly smooth, porcelain hands you know from video games don't actually apply to real life. So don't call perfectly normal female hands "man hands", it's obnoxious.
