gay hall pass
When a man is utterly heterosexual, but he has a mancrush on another dude and- in no way detracting from the aforementioned gentleman's heterosexuality- designates said dude to be his "gay hall pass" in that said named dude is the one other dude that said unnamed gentleman could/would have sex with should the opportunity avail itself.
Prime Minister Justin Trudeau is not only one of the most competent heads of state on the North American continent, but he's also my gay hall pass.
