McAss is what happens to you when you've been stuck in a McJob for far too long. All the cheap, unhealthy and shitty food that most McJob employees consume eventually goes stright to their asses making their asses resemble two dogs in a gunny sack fighting over an Easter ham.

Y: She's cute but look at that McAss, she's got a lot of junk in that trunk
