it wasn't until recently that I actually found out what "wetbacks" meant. I always assumed it was derived from working in the farming industry, and involved sweat.
Kind of akin to "redneck" for the same purposes.
Upon learning the meaning, I figured out that the main reason why I never associated it with it's true (apparent) definition, besides the fact my brain just doesn't work that way, is that I figured most people of that characterization, don't come to the US via water.
Or is "WB" actually slang for another group and I'm wrong again?
