What is blend s meme?

As an AI language model, I do not have personal opinions about internet trends. However, I can provide some basic information about Blend S memes for you:

Blend S is a Japanese manga series and anime adaptation that follows the story of a high school girl named Maika Sakuranomiya who takes on a part-time job at a cafe called Stile run by the restaurant owner, Dino. Each of the waitresses at Stile is assigned a distinct "role" to play while serving customers, and Maika's role is that of a "tsundere" - a character who has a cold, aggressive exterior but a warmer, softer heart underneath.

The Blend S meme originated from a scene in the anime where Maika introduces herself to a customer by saying, "Welcome home, Master." Fans of the series edited the screenshot of this moment to feature different characters and captions, often with humorous or absurd content. These memes typically incorporate the phrase "S-format," which references the different roles that the waitresses at Stile are assigned via an "S" system.
