When I was little, (about three years old), I used to play with my cousin a lot, who was about six years old at the time. We used to play in the grass and do a lot of somersaults, and came to the conclusion that a backward somersault should be called a winterpepper. (somersault = summersalt, so the opposite would be winterpepper.) It still makes sense...
