Waluigi is Nintendo's lanky trickster from the Mario franchise, introduced in Mario Tennis in 2000 as Wario's partner and Luigi's rival. His exaggerated Wa cry became a defining part of the character, repeated across sports, party and kart games and widely clipped by fans online. The short burst circulated through meme edits, soundboards and gaming videos where a single character voice could sum up defeat or mischief. Its lasting appeal is how recognisable it remains without any setup, making the same cry work for a loss, a prank or a dramatic entrance.
