A growing trend for Australian backpackers in Vancouver is to engage in the Vancouver triangle. This involves two men and a woman. One of the men is engaging in vaginal/anal intercourse with the woman on all fours while the other male participant is receiving oral sex. The two men then lean over and passionately kiss forming a triangular shape. Aids, deep regret and ridicule are possible side effects from performing such an act.
"Hey, did you hear Jamie and Markee had a Vancouver Triangle with a Swedish back packer?"

"I can't look Tom in the eye anymore, we got wasted and Vancouver Triangle'd this slut last night"
