An infamous Mac's convenience store in downtown Calgary, a city in Alberta, Canada located in the corner of 7th Avenue and 8th Street SW. So called as it is known for being rather sketchy and crime-ridden, as well as having many people dealing crack outside in the parking lot and around the premises.
Person 1: Hey dude, wanna go to Crack Mac's?
Person 2: No thanks, I don't plan on getting mugged today.
A misnomer used to make McDonald's sound like an upscale eatery. Similar to pronouncing Target as Tarjay, it gives the speaker an air of superiority while also almost definitely proving they are a cornydad. The Ronnie Mac in question is, of course, Ronald McDonald.
Child: Where should we go for dinner?
Dad: I bet we can get a table at Ronnie Mac's Steakhouse!
