Sokka: AAAAARGH! SNEAK ATTACK!

Aang earthbends a wall to block him

Aang: Sokka, sneak attack don't work if you yell it outloud.

"So power up and unleash your finisher move! Just tell us what it's called."

"This hand of mine glows with an awesome power!
Its burning grip tells me to defeat you!
Take this! My love, my anger, and all of my sorrow!
SHINING FINGER SWORRRRRRRRRDDDDDD!!!"

"I FIRE YOU WITH BULLETS NOW."

"640. There is a limit to the amount of adjectives I can add to an uppercut."

Yor: CHARGING GRAPPLE ATTACK!
Hank: Oh my gods, Yor, I swear, you do NOT need to keep shouting out your attacks! This isn't manga!

Hak Foo: ANGRY CROW TAKES FLIGHT!
Uncle: Thank you for sharing, Angry Crow!

"HADOKEN!"

"SUPREME RULER BURNING HEAT THUNDERING DRAGON ROAR ERUPTING FLASH DEMON TEMPEST RAKAN FIST!!!! No good. The name's too long and it doesn't sound good at all... I'm thinking too much. It needs to be boiled down. I need to make it simpler...Return to the basics and put his name in...hmmm....NEGI FIST! Grgh. That's no good. It still sounds bad and there was no time to use the designated pose. This naming isn't working at all!"

"RAKAN-FOR-THE-HELL-OF-IT-RIGHT-HAND-PUNCH!"

"Hard To Avoid... AREA ATTACK!"

Philionel: Take this! All Men Brothers, Hand In Hand!
Philionel: Joyful Reunion Bear Hug!

This is an Ukemi!

"I will shoot at him" said the cyberdemon and he fired the rocket missiles.

"Knife to the eye!"

"Ka... Me... Ha... Me... HA!!!"

"FULL POWER SATELLITE REMOTE CONTROL BOMB"

O, brilliant blade of coldest steel...rend the infinite darkness...and CRUSH MY ENEMIES TO NOTHING! SAVAGE WOLF FURY!

Are they shouting the names of their attacks because they're using voice commands?

Gai: We're going to dock your cockpit into my air unit frame. The call will be "Cross Crash".
Akito: Do I really have to shout that?
Gai: Damn straight!!

Spider-Woman: VENOM BLAST!
Spider-Man: Argh... PAINFUL UTTERANCE! See, Jess? It sounds stupid when you call things out like that. Just sayin'.

Why doesn't he yell out the moves? "Praying Lotus! Five Fingers of Death! Fist of the Tainted Punch!"

Gilgamesh: CHAIN OF HEAVEN!

Baron Diamond: Diamond Knuckle!
Shadehawk: Oh come on. That didn't deserve a name! It's just a punch!

Iska: Its like calling punch, or kick.

Lloyd: Shut up! It gets me in the mood.

I-Have-The-Best-Wife-In-The-Universe KICK!!

For one, the callings out of an attack move like "Rider Kick!" Growing up an Asian kid, this concept is not new to me and is highly acceptable in the Asian culture. But it sounds ridiculous in the American culture because nobody does that. Why would you call out your moves in a fight. Silly right? Power Rangers have been doing this for the last 15 years and it’s still silly.
