1.
Used in Beyonce's song Drunk in Love referring to a sex position. The sex position is when the male is on the bottom laying and the girl grinds and fucks him as if she was sitting on a surfboard. The song lyric goes..

"Then I fill the tub up halfway then riding with my surfboard
Surfboard, surfboard....Raining on that wood, raining, raining on that wood
I'm swerving on that, swerving, swerving on that big body Benz
Serving all this, swervin, surfing all of this good, good"
Fill the tub halfway and ride it with my surfboard.

Yo, dude she did the surfboard on me last night. I felt like I was fucking Beyonce.

The surfboard sex position is when the male lays flat and erect. The female then proceeds to stand over him with one foot on each side of his hips. Next, drop down, swerve on the wood and ride as if it were a surfboard. May also be performed in reverse if preferred
Fill the bathtub half way and I'll ride you like a surfboard.
