It's a piece of word that Dio Brando from an anime called "Jojo's Bizarre Adventure" shouts all the time.
It's also a very popular meme on 4can. It first appeared in a flash film called "mudah.swf". This flash shows a stickman that throws a steamroller on another stickman and screams "WRYYYYY"
Boy: Do we have any bread?
Mom: Yes dear, we have wry bread.
Boy: Awwwwwwww, you know i hate wry bread.
Mom: Go to your room you little bastard!!!!

Wry
Bisexual vampire uses it in a taunting manner to kill a buff man with a road roller and his son uses it as a war cry to display his hatred towards a man who makes mouldy chocolate.
Wry- A high pitched, blood curdling scream. Could be used in anger or a battle cry. Screamo bands have been known to welp out a wry and it is also popularized by the Hunter from Left 4 dead.
