painting her fingernails

Painting her fingernails is when a woman masturbates on the go, like in the bathroom at a party, and when she comes out the tops of her fingernails are all glossy and shiny like she just applied a new coat of fingernail polish.

Guys like girls who paint their fingernails and who will paint them in front of them at a moments notice.

She left the bathroom door unlocked and I accidentally walked in on her listening to Sade and painting her fingernails.
