Just saying hello

In the opening scene of "Forgetting Sarah Marshall" the lead character is surprised by his girlfriend as he steps out of the bathroom with a towel around his waist. By way of greeting, he drops the towel and twists his body back and forth while just below his hips — out of camera range — we hear a distinct "slap slap slap".

"Oh, that's a WW," says Gregg.

"A what?"

"A WW. You know."

"No, I don't."

"It's a weenie wave. EVERYONE knows that. It's just KNOWN."

And thus my husband teaches me something again that I did not know nor want to know, but now will forever have lodged in my brain next to the information about how tofu is made and how to identify lice nits, somewhere behind an image of a liver curdled by cirrhosis.
