What is Home-school High-five?
-A person takes both of their arms and raises them above his/her head and slaps both of their hands together as if giving someone a high-five.
-The idea is that someone like a home-schooler wants to give someone a high-five when they get a math problem right, but there is no one around so they have to give themselves the high-five.
Isaac, that was such a dumb joke! You should give yourself a home-school high-five!
