Got irony?

I don't even know what has happened.  Wtf is up with mustaches?  Like, what the fuck is up with mustaches?  Is this another ironic, hipster, "white" kid thing?   Am I not cool enough (doubt it) to "get" the mustache thing?    Everywhere I look there a gd fauxstache on something.  And you know the worst of it....THEY MAKE EVERYTHING LOOK SO CUTE!  I'm having some turmoil about this (obvi) because I'm drawn to the adorableness that is the mustache symbol, everywhere, but, I think it's stooopid.

I was at the Sanrio store, and I saw a Salutations Feline key cover with a mustache!!!!! I BOUGHT it.  It's so cute....look

Is it a throw back to the seventies, a retro move.  I can't walk into an Urban Outfitters without being assaulted by "mustachized" stuff.  I just don't get it.

This fad/trend has to be coming to an end if they have it AT POTTERY BARN, no?

Anyhow,  I'm simply curious.  Can anyone explain this to me?  The purpose?  The origin?  The end?

Thanks in advance!

Oh, and I'm keeping my hello kitty key cover :)
