man pound

Hold out your hand. Gaze upon it. Then make a fist. Not for punching, cheering, nor jeering; rather, for pounding man.
Limply hold your clenched first towards a friend, passerby, or anyone within reach and proudly proclaim your desire to 'man pound'.
With the blessing of Odin your request will be fulfilled as the person (or animal) you've saddled with such a loft request follows in your stead and, gingerly or not, touches their fist to yours.

Man pound. It is done.

"Uh, hey... do you like wings... on Wednesdays? Yes? Man pound!"
*brandish your clenched hand and ashen knuckles*
