Rippers refers to the exotic dancers who work in the
gentleman's clubs (strip clubs). The clubs are referred to as the
ballet or more specifically the Canadian
Ballet.
American usage: "Hey, let's go to the Canadian Ballet to see the rippers."
Canadian usage: "Eh, let's go check out the rippers tonight." - being that they live in
Canada, stating the location is unnecessary because they all know where the rippers work.
