jocular abbr. for little brown fucking machine, apparently coined to refer to Vietnamese and other Asian female prostitutes during the Vietnam War, but now reserved almost exclusively for compliant Filipinas and Indonesians, whether professional or not. Frequently used in Hong Kong, but never for male sexual partners.

An initialization for "Little Brown Fucking Machine", or alternatively: "Little Brown Fuck Machine."

it's highly offensive and derogatory ethnic slur predominantly originating from the US Navy and used to derogatorily describe Southeast Asian women as sex objects. The term gained some popularity in the travelers community in Hong Kong decades ago, specifically targeting Filipino flight attendants.

although it's barely used now, it's sometimes also seen in the more odd side of porn sites: often advertising Latina or Filipino women with the term "LBFM".
person 1: hey, did you see that jerk at the seat a couple rows down?

person 2: no, what happened?
person 1: that asshole called the flight attendant an LBFM; that's so fucking weird!
person 2: that's gross; I think she's Filipino as well!
