is when two topless females jump in the air while facing each other and hit chests together while in air. The same action as a high five only with tits. This action is done usually at a party or when naked chicks get excited and want to impress the guys.

In order to save muscular movement and energy, a mental high-five may be performed. To successfully complete a mental high-five, one must count from 3 to 1, then tilt ones head forward slightly (like a head bow) and blink at the same time. Mental high-fives can be performed one to one, or one to a group, which can be incredibly handy when one wishes to high-five everyone in a large group. The saved energy from not having to use your arm can then be used for other more important activities, like sleeping, or playing computer games.
"Dude, that was awesome! Mental high five! 3. 2. 1. Go!"
*Nod and blink*

A "Russian High-Five" is when someone brutally elbows you in the face. Generally speaking, Russian High-Fives (also known as "Russian Fives") either break several teeth in the mouth or the nose of the receiver, and it is therefore not advisable to greet anyone you actually care about in such a manner.
John: "Ivan, let me introduce you to my girlfriend next week!"

Ivan: "Do you want me to give her a Russian High-Five?"

John: "No! No Russian Fives this time, please!"
