Expresaseis

Expresaseis is a Spanish internet slang expression that combines the verb “expresar” (to express) with the second‑person plural future tense ending “‑éis” and an informal imperative suffix. The phrase is used to challenge a group of people—usually on social media—to show their emotions or reactions in a vivid and honest way. The word can be understood literally as “you will express yourself” or “express yourself, you all”.

The origin of expresaseis can be traced to a 2016 viral post on the Argentine social networking site TikTok. A user posted a short clip asking friends in a group chat to “expresaseis” in reaction to a trending news story. The video gained attention because of its playful tone and the way it encouraged users to share candid, authentic responses. The expression quickly spread to other platforms such as Instagram, Twitter, and WhatsApp, where it is employed by users of all ages.

Today, expresaseis is most commonly used as a prompt in group chats, live streams, and comment sections. It is often accompanied by emojis or reaction stickers, and it can be applied to situations ranging from emotional moments to playful teasing. The phrase is typically used to signal that a group should respond collectively without judgement, fostering a sense of community and openness. In some contexts, the expression has been adapted into memes where the “‑seis” suffix is replaced with other suffixes, creating variations such as “expresaseis” → “expresamini” or “expresalojos”.

The usage of expresaseis reflects broader trends in Spanish‑speaking online culture, where short, rhythmic challenges encourage immediate participation and creative expression. Despite its informal nature, the phrase has been referenced in academic discussions on digital communication, especially within studies of youth lingua franca and the dynamics of group self‑presentation in digital media.
