回答: @dj_saidez ok, i see that in that situation, b turned the smiling face into a menacing face by replying to a, which added ">" to the reply. then it would work better if you say: ニコニコ顔が怖い顔になっちゃったやん (angry face) ニコニコ顔が険しい顔になっちゃったやん (frowning face) you can use katakana コワイ顔、ケワシイ顔 for consistency with the katakana ニコニコ i kind of get what you mean by ゴゴゴゴ but it's an uncommon expression and unless you're a manga affectionado (especially jojo fans), some people might not understand what you're trying to say.
