Definition & Meaning of "gitch"in English

What does "gitch" mean in Canadian slang?

It is used in Canada, especially in the Prairie provinces (Manitoba, Saskatchewan, Alberta), to refer to underwear, typically men's briefs or underpants. People typically say "Don't forget to pack extra gitch" or "His gitch was showing." The term originated in Canadian English, likely as a variant of "gotch" (from Ukrainian or Germanic immigrant influences), and remains a regional marker of Western Canadian speech, less common in Ontario or the East Coast.
