What is art?

What is Art? Well today got me thinking. What is Art?I mean what makes something "Art" Something new and innovative? Something that catches your eye? Does it have to look "Good" to be called Art?

Observe this; http://www.gaganews.com/wordpress/wp-content/uploads/2009/12/Gaganews-Monster-Ball-Puke1.jpg

Okay, This picture is from the Monster
This picture is from an Interlude (a video/audio that usually plays during a concert usually after a song.)
Well this scene was basically A Girl puking on Lady gaga... and the puke is blue.
..Art?
It could well be Art, considering this could be interpreted in a lot of different ways.
The old life of lady gaga throwing up her new life?
The society in the time when the people she knew didn't accept her for who she was?
No one will know. Because this all can be interpreted in different ways.

BUT
Thats not the case here, well it kind of is but there is more.
The "Puke" wasn't computer generated at all!
It was real!
and she is actually a read "artist" some might call it.
Her Name is "Puking Millie"
She creates Artworks using her own "Puke" on canvas.

My Opinion. I don't find it very artistic at all.
I like art .. But throwing up colours on a Canvas? isn't revolutionary or artistic at all.
I Appreciate Art a lot, but this almost seems like a mockery.
and her artworks sell for thousands?

I give props to her... I guess for using her own technique in make the "..Puke" change colours, i don't know how she does it... I actually don't want to know.

All this is quite disgusting. Hanging up a canvas in your bedroom that smells like someones puke?
Ew. LOL

Tell me What you think? Is it Art or Not?
