Do the anything call, which must end with flow
(usually a Couples Cast movement such as a Courtesy Turn);
"By" means "A Quarter More + Slither";
"By-By" means "A Quarter More, Slither + Slide";
"By-By-By" means "A Quarter More, Slither, Slide + Slither".
Some callers omit the word "Thru" from the call.
(e.g., Turn & Left By-By is a Turn & Left Thru + 1/4 More + Slither + Slide).
