Risky Business Dance

 c32R8tFWCuA A character who is home alone dances around like a fool, singing into a hairbrush. Usually a celebration or declaration of freedom, but sometimes just a way of showing that a character is happy and positive. Very common right after a character has scored a date with their longtime crush. Named for the famous scene of Tom Cruise dancing in his underwear.
