"[anything] [direction]" is defined as follows: "Do [anything], but smoothly turn either 1/4 less or more to end as if the call were "[anything], quarter [direction]". If the [anything] ends in a preposition, you can drop it (e.g. "rip off in" can be pronounced "rip in").
Here are some definitions of existing calls with this concept:
- C1zing = zoom in
- C1shakedown = rip in
- A1explode = stable cast off 1/4 in
- C3Aease off = ends zoom, centers circulate in
- C3Acouple up = split counter rotate in
- [rh waves] C2tandem quarter out = peel right
- [rh waves] C2tandem partner tag = trail left
- [rh waves] C12/3 recycle = recycle left
- [couple] A1beaus fold = hinge right (up to space invasion)
- [couple] A1beaus run = partner tag right (= trade outright, lol)
- [couple] A1partner tag = trade out
- [facing couples] plushalf sashay = left partner tag in
- [rh waves] centers partner tag, ends face right = slither in (say it out loud)
- [eight chain] A1pass in = pass in. Sadly, they're not equivalent in general because A1pass in uses a plusface in rather than a A11/4 in.
There are also some nice things that don't have names, like "little left" to get from a right-handed quarter tag to a starting double pass thru.
