Russian Underside

the russian underside is when your lady gets on top of you upside down and backwards and masturbates you with a 400 pound salmon while you masturbate her with a snow fox.

"Natascha, I think we need to spice up our love life"
"Boris, if you go to the fish store and get some salmon, we can do the Russian Underside and things will be so much hotter!"

underskirt

A slip is a woman's undergarment worn beneath a dress or skirt to help it hang smoothly and to prevent chafing of the skin from coarse fabrics such as wool. Slips are also worn for warmth, and to protect fine fabrics from perspiration.

Guy : "You could see her pink underskirt hanging below the hemline"
---
Mom : "Monica what will you be wearing for the dance today ?"
Monica : "Planning to wear the cream long dress, mom"

Mom : "Thats nice, but remember to wear a underskirt as it is a bit transparent"
----
Principal : "Girls should wear underskirts with their dresses for modesty"

Alabama Underbite

When an inbred looking girl without teeth is going down on you and then sucks your balls from below, not under, like a fish to bait.

Ol' girl was going at me good and then dropped her dentures and hit me with an Alabama Underbite.
