snard lumps noun snow and ice clumps that build up under the fender of the car CANADA In eastern Canada, they have been called “snowbirds”.
A snard lump is the collection of ice and snow stuck under the car fender in comparatively warm winter conditions. They keep building up while you are driving, and fall only if you kick them off (in the garage, they form a solid lump behind each wheel). — Chris Thain, Cold asaBayStreetBanker’sHeart, p. 142, 1987
