BTW, Chambers also gives one meaning for "shag" as:

 a US dance related to the jitterbug but with shuffling footwork, first
popular in the 1950s and 60s;

and later

(verb intransitive) to dance the shag:

which is (sadly) what the good ladies of South Carolina meant when they
exclaimed "let's shag!"
