Give yourself a WARCRY!

[AgnosticMessiah]

CARROTS AND PEAS!!!

 

[Scorched_Cascade]

*Cultist voice* "DO YOU HEAR THE VOICES TOO?"

Alternatively I'd use one the relevant ones from here:

 

[White_Lama]

Maybe more "shouty" than that, but you get the point

 

[Brendan Stepladder]

HEEEEEEELLLLLOOOOOOOOO!!!!!

 

[Reiper]

Just about any quote from the dow2 commissar lord / warlock

 

[Ix Rebound]

CHEESE! FOR EVERYONE!!!

and then my army launches the explosive cheese catapults

Captcha: grilled cheese
no just regular cheese

 

[CrazyJew]

God DAMNIT OP, did you have to ninja me in the very first post?

 

[Unsilenced]

I would probably just go with the classic manic screaming. As for an actual war cry, I'd go with either: YAKA KATOGI!
THERE CAN ONLY BE ONE!
FOR THE EMPEROR/EMPIRE!
FOR PONY!
or FOR THE MADGOD!

That's my line.

Also: FOR THE HOUSE OF DEMENTIA!

 

[PUR3_GAM3R33]

WOOOOOOOOOOOOOOOO!!!!!(Kinda like Ric Flair) followed with a boisterous laugh.

 

[Shinsei-J]

A calm "Dance with me my friend" as my Pathfinder rogue.
Feel my fever!!!

 

[Fijiman]

That's my line.

And I thank you for reminding me of it.(although how I'd forgotten about it I'll never know)

and then my army launches the explosive cheese catapults

And by reading that I instantly see cheese catapults flying through the air at the enemy while flinging flaming fondu at the same time.
