wtf@ the ending....

Yeah I need someone to explain this.
Odd people.
It kinda seems like the guy that was holding the girl in the air was kinda grinding on her ass while he was holding her and she noticed that shyt... so she slapped the shyt out of him??? If you watch the clip... after she slaps him she looks down at his dikk like... "I felt that shyt... you ain't slick".
