Trampling
Trampling is the act of walking on something repeatedly so that it gains pressure effects.
Scientific use
Trampling may be by animals and cause effects. Called the trampling effect on the soil. Ol Pejeta Conservancy use the effect of livestock to facilitate grass growing as part of its wildlfife management strategy.
When carrying out investigations like a belt transect trampling should be avoided. At other times it is part of the experimental design.
Trampling can be a disturbance to ecology.
Sexual activity
Trampling refers to the sexual activity that involves being trampled underfoot by another person or persons. Trampling is common enough to support a subgenre of trampling pornography.
Because trampling can be used to produce pain, the trampling fetish for some adherents is closely linked to sadomasochistic fetishism.
A similar fetish is to imagine themselves as being tiny under another's feet, or being normal size, but being trampled by a giant person. This is known as "giant/giantess fetishism" or macrophilia. It is not the same as trampling.
The most common form of trampling is done by a female (in rare situations by a male) walking on a male or female submissive and is usually done barefooted, in socks, nylons, or shoes. The trampler will predominantly walk, jump and stomp on the person's back, chest, stomach, genitalia, face and in some rare instances, the neck.
