A promo girl is a unusually thick girl with good physical attributes who is willing to spend her working life wearing the following, a bikini, a swimsuit, micro skirt, cropped top, boob tube. Whilst standing in front of some crappy cheap product at a exhibition which is aimed entirely for purchase by males. You would imagine that they would have low self esteem but normally they are so engrossed in the business of bending over the car that they actually feel they are making a difference to the world.
Not to be confused with sluts who actually know what they are doing.
Man 1) Has that car company hired in a bunch of whores to stand in front of their cars.
Man 2) No they are promo girls and they won't always fuck for money... Damn shame though!
