There is a scene in the movie Beautiful Girls:
Willie: How they doing?
Paul: You kidding me? All he ever thinks about is Darian Smalls.
Willie: Come on! Still?
Paul: Still! Nothing changes around here, Will. Every time Sharon looks at Birdie's face and sees him thinking about Darian, it's translated into another ugly pound when she looks at herself in the mirror. Have you seen her? She looks like one of those kids Sally Struthers feeds paste to.
I can't figure out what "pound" means here. It can't be a dog pound or a car pound. Here is a clip of this scene I found on YouTube.
