look up any word, like the eiffel tower:
1. Battlecry, often used as an interjection and only very rarely against friends or aquaintances.

2. Secondary interjection most often used in a situation where words fail and emotions (anger or rage) prevail.

This word is attributed to a series of syllables that left the mouth of one Denzel Tane (changed to protect some guy) after a grevious series of assaults against his mentality from a playstation video game.
If Taylor says to Denny, "Bring it!"
Denny should respond, "Achikaka!

If Denzel is orchestrating a battle against Tayzer and Paulzed, he should use the battlecry "Achikaka!" when initiating the assault.
