If a farmer did it, it can't be good! 
all kidding aside, it's probably the same as a chicago 3-way, do a search, this topic has been around before on this forum...

Out here we call it a coast 3-way. All I know about them is that they are a pain in the butt.

What I call a farmer switch is still perfectly legal.
The single pole farmer switch is bringing power to the receptacle first, and then sending a two-wire cable to the switch. The white supplies power to the switch, and the black brings the switched power back to the receptacle to use.
A farmer threeway is the same thing, add another switch with a three-wire - the whites are tied together, red and black travellers, and the black between the receptacle and the switch is the return, as required by 200.7(C)(2).
*Note: In my picture, I had red and white travellers - same difference. Easier to describe verbally with red and black travellers, and then I went looking for my picture.

Real, pull a 14-2 from a receptacle to the light. Pull a 14-2 from the light to the switch. This is what I've been taught as a farmer switch (single pole). Add a switch and some three-wire from that switch, and you have a farmer 3-way.
Where am I losing you?
Wrestless, that's the problem with slang. I'd call a neutral-switched light a Chicago.

We always called this a switch loop. This is the "no neutral at the switch" that home-automation fans disdain.georgestolz said:
Plus, always feed the far switch with the white through switch boxes, and use black and red as travelers.
