A crappy misinterpretation of the word hadouken
and sometimes shoryuken
from the Street Fighter video Game series. This is usually the case with games on older video game systems such as the Sega Genesis or Super Nintendo Entertainment System as the sound quality is not realistic or clear, so it is sometimes hard to determine what is actually being said.
A person is playing a game of Street Fighter Alpha 3 (with the character Ryu) and he performs the Hadouken(Ha-doo-ken) or Shoryuken(Sho-roo-ken_attack.
Ryu screams out the word "HADOUKEN!"
The player (out of sillyness and misinterpretation) says the word HAYOUGET! but does not know that the character actually says "Hadouken!" instead.
