When a girlfriend and boyfriend agree to an open relationship whilst the boyfriend is in Thailand. This agreement allows both parties to hook up with WHOEVER they want during this holiday period. NO EXCEPTIONS.
Friend 1: Why are you hooking up with that sexy random?
Friend 2: Me and my boyfriend have a Thailand agreement.
Friend 1: Oh you can totally hook up with whoever you want... no exclusions.
