Dancer Liam Ferrari posted a video this week that kind of defines dancing like no one is watching. On Facebook, he uploaded a comically sexy clip, shaking his booty as his pants slide down.

"When [you're] home alone," quipped Ferrari—though it's a safe bet most of us don't have the talent (or abs) to pull off this routine.  The Day-Glo undies are adorable, though.

Below, enjoy a belated Christmas present.
