Mind Five is simply a High Five from a distance or when you can't use your hands for a High Five
The Background of this consept is from my workingplace, i am an carpenter and once me and my workbuddy would take a high five but he was on the roof and i was downstairs so we managed to find up Mind Five
If you and your buddy stands on each sides on a road and wanna do a high five but cant because the distance is to long, take up your hand and make it look like you ar saying Mind Five with your mouth.
Here is a video but this is not the actual mind five:
