I call them border jumpers.
” . . . border jumpers.”.
Yes.
Colloquialisms and slang sometimes take a generation or two to repeat or return. For instance, in the 1920s, the term “hottie” was used in reference to those the speaker found sexually attractive, and then about 80 years later it returned to use for a period of time.
During the 50s, in the Eisenhower administration, a term for south of the border illegal aliens was “wetback”, alluding to a method of entry, i.e. crossing or swimming the Rio Grande River.
