A category above a plain old swampdonkey. A shwampdonkey (shwamper, shwampdonk, etc...) only receives this title after having been shwamped in a shwamp (fucked by multiple guys, outside, on the {preferably damp} ground). Until that point, she's still a swamper.
Tera's a shwampdonkey! Look at the mud stains on her knees and back! Fuckin' shwamper!
