Just everything there

A guy wrote `:(){ :|:; };:` in a comment on facebook.
I launched it on my machine, and resource was temporarily unavailable.
Googled this and that.
Then launched `:` - resource was temporarily unavailable.
Then just did echo "a`:`b" - resource was temporarily unavailable.

My questions are:
- wtf was it
- where can I google it

(No, I'm not looking for an ip address of a loser, I know it)

P.S. Fuck, it was a fork bomb. Captain. It was so long ago.
