ATM machine
n.— «Targeting immigrants is not unique to Oakland. Last month Richmond police were called to investigate the fatal robbery of an El Salvadoran immigrant. The city’s street thugs sometimes refer to Latino and Asian laborers as “ATM machines.”» —“Wildlife Veterinarians Give Bird Feather Implants” in Davis, California KEYE-TV Feb. 13, 2007. (source: Double-Tongued Dictionary)
“ATM machine” is an incorrect
expression, regardless of whom the
speaker is, because of the obvious
redundancy: the “M” already means
“machine”. The allowable forms
are, either just “ATM” or, “AT
machine”.
