Derived from the italian for penis, Minchia is used as a noun describing ANYTHING that is cheesy, stereotypical, self-conscious or just plain minchia. This definition is minchia in itself.
1) In music - damn, I've really had enough of that death-by-nostalgia Franz-Ferdinand minchia
2) In food - say, shall we go out for a minchia meal?
3) In the arts - jeez, the whole concept of theatre was minchia from the start
