FXで有り金全部溶かす人の顔 FXで有り金全部溶かした人の顔
(FX de Arigane Zenbu Tokasu/Tokashita Hito no Kao)
A meme originated from Ponoka-sempai's face in Ai Mai Mii.
Features a notable wall-eyed "derp face" with simple, thick-outlined, empty eyes and a small, open mouth.
The "FX" in question is the FOREX, or Foreign Exchange Market, which is often ridiculed in Japan (especially 2ch) as being a place for get-rich-quick schemes that often backfire.
