Maybe you showboated to much to the point where it is Unsportsman like? Like after a goal you start screaming and doing front flips, and making the other team feel like they stink. It could be a penalty if you take it too far. My friend got a penalty for screaming "Yard Sale!" in the middle of a game when a kid got, well, yard saled. It is entirely possible to get a penalty for that, but it usually doesn't happen unless refs are really strict and/or have a stick up their butt (
