>>>Mcxxxx ..."micky mouse" pejorative.

I suppose the adult population might make the mickey mouse reference, but certainly not Gen-Xers. (the first time I heard someone tell me something was too 'mickey mouse' for their taste I thought "what a stupid phrase." I didn't realize it's popularity among my elders until afterward.) To me, Mcxxxx could only be in reference to McDonalds.

I have heard my college colleagues refer to their McJobs for years, but I didn't realize the word actually made its way into any dictionary.
