What does yump mean?
Yump is a regional English word with two established clusters of meaning. In Canadian usage, especially in northern and ice-road communities, a yump is a rough patch of road or frozen surface that throws vehicles upward or makes them bounce violently; to yump is to move with such a sudden jolt. The word is therefore vivid in descriptions of winter travel: a route may be difficult because of its yumps, and a driver may yump over a ridge. In older or dialectal English, yump can instead mean to belch, and it is sometimes extended to vomiting. These uses are geographically marked and informal, so the word would sound unusual in formal general-purpose writing. Even so, yump is memorable because it names a very specific physical experience, whether the abrupt lift caused by a rough road or the sound and action of belching.
A rough or uneven stretch of road, especially an ice road, that causes a vehicle to jolt or rise suddenly.
"The driver slowed as the truck approached the first of several yumps."
Concentrated in Canadian English, particularly in northern transport and ice-road contexts.
To move with a sudden upward jolt, especially over rough or frozen ground; in British regional usage, to belch or vomit.
"The old truck yumped over the rough patch, and everyone in the cab bounced upward."
The transport sense is chiefly Canadian and usually describes an involuntary jolt. The belching sense is regional and informal.
A countable noun with the regular plural yumps.
"The driver slowed before the worst yumps on the route."
The Canadian ice-road word yump names the rough stretch of frozen ground that can turn a winter drive into an unintended launch.

Etymology of yump
The ultimate origin of yump is uncertain. An imitative origin has been proposed for its older belching sense, reflecting the sound associated with the action. The Canadian transport sense developed around the idea of a sudden upward jolt, although its precise historical relationship to the older sense is not firmly established.
