Yet another Australian expression of surprise, disbelief ar anguish. There is quite a collection of these (see tags below).

Usually said with each word pronounced very separately and deliberately, but is quite often uncontrolled. The first thing I said when I turned on the TV and saw the World Trade Centre collapse was:

a word used usually during the holidays, after opening an amazing present. Also was used in the movie StepBrothers.

1. An expression that is used when someone is surprised, amazed, or disgusted.

2. it is the greater version of "holy shit"

3. it is very popular phrase among military personnel.

When something surprising with a huge magnitude happens (IE: Pregnancy, The rapture, and/or Bon Jovi making a serious comeback) this phrase is used to express disbelief

What the hell is going on?!

We all know that fat ass that lives up north and its kewl to let him come in your house but if a creep does its bad(personal thought)

Definition 1:
A long expression used in reaction when something unbelievably crazy has just occurred / been witnessed / someone has found out about.

Definition 2:
Can also be used to describe the actions of an individual or group, who has just completed something of remarkable skill or achievement, and are worthy of comparison to Batmans skills.

Derived from the Robin ‘The Boy Wonders’ TV show catchphrase;

“Holy (insert object / person / event here) Batman!!”
