is a high-five
used whenever three guys simultaneously want to give each other high-fives
. To employ the use of the high-fifteen means that none of them has to feel awkward and left out while he stands there watching his two friends happily high-fiving
one another before he can do the same.
By the the time Eddy and I had finished high-fiving, Bill had lost his excitement and even though he still high-fived
me, I could tell his heart just wasn't into it. We should've used a high-fifteen instead.
