Used in British Columbia and Alberta. Gitch and gotch are variants heard east of Alberta. It is also acceptable to append -ies to any of these variants as a diminutive (like Johnny versus John), especially when referring to the underwear of male children. Gonch is both the singular and plural form: I had a pair of gonch in hand. The rest of my gonch were in the drawer The term is becoming more widespread in use as a result of the rise in popularity of Vancouver-based undergarment company GinchGonch. A gotch-pull or gonch-pull is another name for a wedgie. The term is also used in compound words. Long-gonch is another term for long, winter men's underwear. A gonch-rotter is a release of virulent flatulence, implying that the virulence destroys the underwear.
