DFB 

A dance floor boner. An inconvenient erection that results from grinding with a girl. In the occasion of such an incident, the male dancer with the DFB finds a replacement male dancer as he "headbands" the DFB, relocating it under his belt. He then resume dancing with his female partner.

Hey Chad, can you dance with the girl for a second? I've got a DFB and I need to strap my stuff down.
