These are typically done from a setup commonly called a "rigger",
and involve two offsets. The first is the "rigger offset", and is
always taken out. This consists of the end two people moving
(usually) forward or backward, dragging the adjacent person with them,
until they are facing in or out of a parallelogram. The call is then
done in that parallelogram. When it completes, the outer pairs of
people move as required to center themselves in (usually) a new
"rigger" formation.

If the call is a shape-changer, the result of doing it in a parallelogram
might be an offset formation. In this case the outer people move as required
to center themselves.

Facing directions don't matter in any of this. All that is required is that the
outermost people know which direction to move. The "Rightrigger" and "Leftrigger"
concepts tell them to move right or left, respectively. The adjacent person
goes with them.

One may also hear "Frontrigger", telling the outermost people to go forward, or
"Backrigger", telling them to back up.
These concepts can also be used in 1/4-tag-like setups. The outside people
both move in the direction indicated (which must be consistent), and then
everyone does the call in offset lines or columns.

The final recentering operation is sometimes used as a call in its own right:
"Like a Rigger".
