Per Karl Fostvedt:
- elbow hook: trailing arm wrapped around skis, similar to a stalefish
- blunt wrap: elbow hook trailing arm plus your lead hand reaching over your body grabbing a seatbelt blunt. It's a double grab and your lead hand grabbing tail is what makes it a blunt + a wrap
That being said, what you're describing is often just called a blunt wrap. It doesn't really matter what you call it but it is worth noting that a blunt wrap is actually a double grab
