This is a trick I do sometimes to go around corners. It’s a bit more fun than just turning. It’s not really a G-Turn, but starts as one. You do a G-Turn style nose wheelie and carve it quickly 90 degrees, then swing the rear wheels around like an end-over. So you have gone around a corner, and are now going backwards. From here you can just pivot back to forwards, pointing whatever direction you want. For lack of a better name, and because it looks like you are starting a G-Turn, I call it a G-Snap. To me this is a fun thing to do in street skating.
