"S" Stands For? is a video edit series that took the opening sequence of the fall 2017 anime Blend S, in which characters spell out "Smile Sweet Sister Sadistic Surprise Service," and swapped in scenes from other shows1. Within days of the anime's premiere, YouTubers were replacing those lines with everything from Sasageyo chants to JoJo screams, kicking off one of the defining anime remix formats of late 2017.

Overview

"S" Stands For?, also known as Smile Sweet Sister Sadistic Surprise Service, is a video and image parody format built around the opening sequence of the Blend S anime, where the main cast take turns declaring what the letter "S" stands for2. Editors keep the cheery visual structure and audio beats of the OP but replace each girl's line with clips, screams, or catchphrases pulled from other anime and pop culture1.

The joke works because the original song is bright, sing-songy, and rigidly rhythmic, so any hard-cut insert lands with a jarring punchline. Popular targets include shonen shouts, MS Paint drawings, and mashups that swap all four "S" words with unrelated media3. The Urban Dictionary entry sums it up as "a meme that has the intro of a anime called blend s that goes smile sweet sister sadistic suprise serivce"4.

The Blend S anime, adapted from the yonkoma manga of the same name, aired its first episode on October 7, 2017, opening with the now-famous chant of "Smile Sweet Sister Sadistic Surprise Service"2. Four days later, on October 11, 2017, YouTuber BlueEyes uploaded a parody that spliced the Sasageyo scene from Attack on Titan into the OP's cadence, and the video passed 317,000 views within three weeks1.

Blend S itself was produced by studio A-1 Pictures; the anime is the subject of the meme, not its creator. The earliest known remix is credited to BlueEyes on YouTube, though "S" Stands For? edits quickly became an open format anyone could riff on3.

How It Spread

The format snowballed on YouTube in the two weeks after the Blend S premiere. On October 13, 2017, YouTuber Paulo Gabriel posted a longer remix that stitched together scenes from JoJo's Bizarre Adventure, Attack on Titan, and My Hero Academia, treating the OP as a jukebox for other anime punchlines5.

By October 21, 2017, YouTuber sleepstr had posted an MS Paint recreation of the opening, stripping the animation down to crude drawings while keeping the song intact1. Five days later, on October 26, 2017, the channel Animejodas fan return uploaded a compilation of "S" Stands For? remixes, signaling that enough parodies existed to warrant a highlight reel6. The format also seeped into anime subreddits and Discord servers as a reaction template throughout late 20173.
