Hopsydoodle 

When one becomes so excited one cannot contain oneself and bursts into an involuntary “happy dance” ala Snoopy's classic dance for his supper bowl.

Example:“You see them horses hopsydoodle into that pasture soon as you opened that gate!” or... A wife, upon rejoining her newlywed husband, following the consecration of their nuptials, and witnessing him doing an “end zone dance” in the kitchen (but unaware he had just seen his favorite team score on ESPN) remarks seductively, "Well... aren't we a little hopsydoodle this morning!"
