Haroo! 

An Irish yell of victory or excitment.

After Brigadier General Thomas R. R. Cobb's Irish Regiment of Georgia pushed back Lieutenant Colonel St. Clair Mullholands Irish Brigade, a Captain (3 stripes on the collar) took off his hat and started yelling "Haroo! Haroo!" and the rest of the regiment cheered "Haroo!"

Hadookie 

A real-life special attack achieved by reaching down the back of your pants as you fart to catch the gas in your hands, and then thrusting your palms forward, sending a surge of invisible destructive spirit energy flying towards your opponent.

I knocked my roommate unconscious by focusing my chi through my colon and into my cupped hands, and then into his face accompanied by a cry of "Hadookie!"

Harbooger 

When you have an itch on the rim of your nose and when you scratch it a booger gets on your finger. You try to hide it by putting ur finger in your mouth and bit down on your nail while savoring the booger. You are confident no one saw you but if they did you will recruit your older brother to tell everyone you never have ate a booger in your life!

Tom: Jim, did you just Harbooger?!!!
Jim: No way man! There was no booger! Just scratching!! No Booger!!
