My current girlfriend sent me this as we had discussed girls fighting https://www.youtube.com/watch?v=0MDtZ4tRVgI :) ???
Why not? In high school, guys did ball taps to other guys so it doesn't surprise me that girls would do similar.
I honestly never heard of it, but if it leads to catfights, then hell yeah ;D
Guessing they're making fun of guys and the weird ball taps
