mco 

Pronounced M-Ko, Mco is a term used to label someone, something, or some place that defines the epitome of "middle-class obscurity": ie. an example of extremely typical middle-class conformity to the point where nothing remotely interesting can ever come of it or from it, or where even the slightest exposure to the MCO person, item, place or thing may render your existence culturally irrelevant through osmosis.

Mco can refer to people who live in a typical middle-class way, typically middle-class ideas and values, typically middle-class objects, or typically middle class objects.

Mco is the direct opposite of avant-garde (avgar).

I can't live in that house; it is just too mco. Before I knew it, I'd be wearing Boden and cooking Nigella recipes.

Mentally checked out.
The thought of a future together doesn't excite you.

MCO of the world . Less and less involved.
