look up any word, like pussy:
When your having sex with a girl in the missionary position and she starts patting your bum cheek with one hand in an effort to make you go harder and faster. If she uses two hands then its commonly referred to as "double basketballing".
I was doing my thing all slow and sexy and she started "basketballing" me. I ignored it and then she started the "double basketballing" me into action. Fair enough.
