Sexual poisition:

The girl lays stretched out, face down on the bed (like a 'plank'); the guy straddles her and enters her from above and behind; his balls spank her ass with each thrust. Spanking + plank = Splanking! This position makes the pussy truly tight!
Bro 1: All chicks I have fucked love splanking!

Bro 2: What's splanking?

Bro 1: It's my signature move! The chick lies down like a plank and my balls spank her while I fuck her from behind!

Bro 2: That must make her pussy super tight.

Bro 1: That's the point!
