I did a search for "loosing" at one point, and it was amazing how many posts came up.
Phew...none of them was me.
Me neither! *High five*
Me neither! Down low!
Wooot! On the flip side!
Let's do it Top Gun style!
Um, way to go ace fighter pilot man!?! Have a high heat-seeking missle!?!
From Wikipedia: One such variation is the "flipside", also called the "windmill"; this method begins like a regular high five, however upon meeting up top, both high-fivers continue to swing their arms downwards until they meet again in a "low five". This method is depicted in the feature film Top Gun repeatedly.
