Feliz Jueves, also known as Running Asuka, is a GIF and viral clip featuring the character Asuka Langley from Neon Genesis Evangelion briskly sprinting toward the viewer to wish them a Happy Thursday.
Its wide usage comes from the large contrast between the innocent appearance and nature of the message and the extremely dark context from which it originally derives. On Thursdays, "Feliz Jueves" will often appear posted by users across social media, particularly in the Hispanic community.
