The practice of going up behind a woman in a nightclub and putting your fingers inside of her without her consent, as part of a dare or contest. A form of sexual harassment.
"Hey man, I'm feeling extra misogynistic this evening, want to have an underhanding contest?"
"Sure, I also have no decency and want to harass someone more vulnerable than me, lets do it!"

A snide statement that is hidden behind what seems to be a polite one. It can be an inside joke, but can also have negative connotation.

The action of female grasping to line up the penis for proper angle of penetration prior to intercourse; woman on bottom. Most common when a guy (freehanded) rubs the head of his penis around the pussy lips and doesn't insert; frustrated the female will grasp the dick with a underhand grip and slid it in. The man will immediately feel gratified as the woman was unable to hold out any longer and executed penetration. Excellence is measured when a woman who plays extremely hard to get gives an "underhand slider".
Matt: Last night I was messing around with Tiffany and to my surprise she gave me an "underhand slider"! I was teasing the shit out of her and making her quiver...she couldn't take it and underhand slid it in.
Zak: Those are the best.....Kristen holds out and acts like she doesn't want it but I get an "underhanded slider" nightly.
Jimmy: I get underhanded by Sam all the time....she love the dick!
All: HAHAHA
