The Great Khali's signature Taunt that involves him raising his arms in the air and shouting out "YEAHHHHHHHHHHHHHH" (The English word "Yeah") is dubbed as the:

Stronger Than You Taunt

   
The Great Khali's "Stronger Than You" Taunt

The Great Khali generally does this taunt after he puts a wrestler to the mat, shoulders down, as a display of his power, overwhelmingness and dominance. The Great Khali raises his arms towards the skies and roars.

This taunt is usually followed by Khali pointing his finger towards a booing fan or spectator and saying the phrase "You..." or "You suck" or "Will see you" or "Hey.." (In ENGLISH). The Great Khali's Taunt has been subject to quite some criticism, but its just what he does, thats the part of his overall character's attitude.

Earlier Khali used to shout "ARRHHHH" and similar stuff, but lately this has been replaced by the phrase "Yeah". Khali was first seen using this taunt following his first match in SmackDOWN! and continues to use it to this date, in his matches. It should also be noted that sometimes, a shout isn't included in this taunt.
