Slush
Canadian SlangDefinition
Wet, partly melted snow—often dirty and salty—that accumulates on streets and sidewalks during thaws.
Examples
"I wore my rubber boots because the sidewalks were buried in salty slush after the thaw."
"The streetcar splashed dirty slush all over my jeans as it rolled by."
"By noon, the snow had turned to grey slush that made every crosswalk a soggy mess."
