Definition & Meaning of "gonchies"in English

What does "gonchies" mean in Canadian slang?

It is used in Canada, especially in the Prairie provinces (Manitoba, Saskatchewan, Alberta) and parts of British Columbia, to refer to underwear, typically casual or everyday wear for men, similar to "gitch" or "gotchies." People typically say "Pack some clean gonchies for the trip" or "He ran around in his gonchies." The term originated in Canadian English, likely from Ukrainian or Germanic immigrant influences ("gonch" meaning "underwear"), and remains a regional marker of Western Canadian speech.
