Upper case M followed by lower case c: preface denoting something that is cheap, shotty, dead-end and highly standardized with little real value. Examples include:

McMansions: large, ugly, expensive houses built to order but according to a standard design by companies catering to those with money but not taste. Often prized by the newly rich who retain pedestrian middle or lower class tastes.

McJobs: low-wage, low-skill employment with no benefits and few prospects for advancement, as in WalMart.

McSchool: an unaccredited college or university that promises potential students that their marginal or worthless degrees will open career paths for them.
1. Mike got himself a Mcjob the other day, flippy burgers at the local McDonald's.

2. I can't believe my friend Janet just spent thousands of dollars on some on-line McSchool when she could have gone to an accredited state university or community college for half the money!
