In hockey, a butterfly is a goal-tending style in which the goalie keeps his knees together and his feet slightly apart.
Instructions HERE on how to do it in case you're interested.
We have a hockey team in Nashville (the Predators). I've never attended a game but would like to. I've been to the arena for concerts and events. It's called the Sommet Center now but was the Nashville Arena and then Gaylord Entertainment Center. I have negative feelings toward Gaylord since they dismantled Opryland Theme Park when they sold it to become Opry Mills Mall. As Joni Mitchell sang, "They paved paradise and put up a parking lot." This got a derisive, resounding, "YES!" Sunday when Richard Sher asked if we were upset about Opryland becoming a mall. It definitely hurt tourism.
Gaylord also got rid of TNN (The Nashville Network) which was on cable and did so many other despicable things I can't mention on here. They still own the Opryland Hotel here and in Florida (Palms), Texas (Texan), and DC (National). My cousin worked for the bastards for about 20 years and really liked her job. She did training and traveled quite a bit and helped open some of the hotels, too. She doesn't read my blog.
