People usually gloat or they don't. Obviously you keep quiet when you are down, so you don't find out until they win. Some people like to say look at me. Others don't like people looking at them. I'm ok with either as long as it's not over the top with the "look at me"
Most people celebrate touchdowns with a spike, hi-5, a small dance, etc. Planting a cell phone in the goal post is a bit much. In other words some celebration is good.
