brokeback mountie 

a usually masculine member of any military, fraternity or law enforcement agency that is such a hard-ass, dickhead that heterosexual people under their command become temporarily sexually uninhibited and submissive in their presence as a way to show allegiance.

Lt. Fisher enjoyed seeing me scrub the latrine floor in my boxers today-he's a real brokeback mountie!
