Many people define the stinkface to be when one sticks their ass in another's face, leaving their face smeared in crap. This definition denounces those other definition. The stinkface originated as a wrestling move; since this move does not cause any "injuries," it is used mostly to embarass the victim.
Just to establish the definition of a stinkface, it is a wrestling move that (usually) involves two people. In classic wrestling, one opponent is thrown against one of the poles, and sags to the ground, defeated. The other opponent then backs their ass into the victim's face, rubbing the fat of their ass around and smothering the victim.
The stinkface has many uses. Let's explore those:
1) Humiliation: The original purpose. To humiliate an opponent rather than injure them.
2) Punishment: To some people, receiving a stinkface is not pleasurable, so this move can be used as a consequence.
Above, it was mentioned that stinkfaces can include more than one person. This option relates to Use No. 2: Punishment. The victim is obviously reluctant to receive the stinkface, so sometime another person is needed to restrain the victim.
Types of stinkfaces:
1) Regular: The victim sags against the pole (or wall) and the stinkfacer backs his/her ass into the victim's face and grinds.
2) Against-the-Wall: The victim sits up straight against a wall and is smothered with ass when the stinkfacer closes in. This is also a type of facesitting
Man-to-Man Stinkfacing: When a man stinkfaces another man, this will usually be a prank.
Man-to-Woman Stinkfacing: This does not happen a lot, but is probably a prank as well.
Woman-to-Man Stinkfacing: This will most likely be wrestling humiliation, or part of femdom practices.
Woman-to-Woman Stinkfacing: Part of wrestling humilation.
When men do stinkfaces, they wear pants.
When woman do stinkfaces, they wear thongs or lingerie.
Stinkfaces are simple enough to understand, with this handy definition.
