John: Leave me alone!
Tyler: You a brokeback mountain as nigga!

Tyler: I'm not going out tonight, I want to stay home to watch Tope Chef and make pan broiled halibut.

Mountain-ass 

noun, the medical condition experienced by female ski resort season-workers wherein rapid and protracted intake of high-calorie, often fried foods (usually justified on the grounds of perceived increase in physical activity) causes expansion of a formerly attractive posterior beyond normal dimensions.

Dude1: Man, this season was too f**kin' ace, but I'm looking forward to rotating back to the world and seeing some girls without mountain-ass.
Dude2: Quite.
