Jajajajajaja!
From Euphro
Onomatopea usually attributed to the sound spanish-speaking players make when they laugh, in contrast to the English-speaking player's "Hahahahahahaha!". In spanish the letter "j" sounds like the english letter "h".
"Huahauahuahuahau!" and "Haiuehauheaiuheiauheaiuehaiuea!" are Brazilian versions of the "Jajajajajajaja!"
