are you sure about that meme

“Are you sure about that?” is a long‑running reaction meme used to humorously question someone’s confidence, facts, or decisions, often by cutting in a short video or audio clip right after a bold statement.

What the meme is (quick scoop)

  • It’s a reaction line used to express doubt or call someone out when they sound overconfident or clearly wrong.
  • You usually see it as a short clip dropped into edits, TikToks, or YouTube videos right after a claim like “Trust me, nothing can go wrong.”
  • The joke is the contrast: someone speaks with confidence, then “Are you sure about that?” instantly undercuts them.

Main versions people mean

There are a few distinct “are you sure about that meme” clips that people might be referring to:

  1. John Cena green screen (classic)
    • Originates from a 2016 Cricket Wireless hidden‑camera ad where John Cena bursts in and shouts “Are you sure about that?” while ripping a paper.
 * A green‑screen version of just Cena saying the line was uploaded to YouTube and became a template for edits, getting pasted over other videos whenever someone says something obviously false or dubious.
  1. Tim Robinson (I Think You Should Leave)
    • From the Netflix sketch show I Think You Should Leave with Tim Robinson (season 2, episode 3), where Robinson’s character repeatedly asks, “Are you sure about that? Are you sure about that?” while staring at the camera.
 * Popular on TikTok as a sound to mock misinformation, bad takes, or questionable life choices; creators overlay him on top of something they want to call out as wrong.
  1. Invincible / Omni‑Man “Are you sure?” trend (newer)
    • From Invincible season 1, episode 1: Mark says he’s finally getting his powers and his dad Nolan (Omni‑Man) skeptically replies “Are you sure?”
 * In 2025 this scene blew up on TikTok as chaotic edits: people loop, distort, or spam Omni‑Man saying “Are you sure?” and drop it into wild “brainrot” compilations.

All three sit under the same general idea: a confident claim gets instantly checked by a skeptical voice.

How people use it now

  • Fact‑checking jokes: Someone posts an obviously wrong statement; another person replies with the clip (or just text “are you sure about that?”) to mock it.
  • Calling out overconfidence: It’s common in edits about relationships, money, gym goals, or quitting jobs—any time someone is clearly overestimating themselves.
  • Layered “brainrot” edits: Especially with the Invincible version, editors stack filters, zooms, and audio distortion, spamming “Are you sure?” to make it intentionally overwhelming and absurd.

A simple example: a clip shows “I’m definitely waking up at 5 a.m. every day from now on” followed by a smash cut to Tim Robinson or Omni‑Man asking “Are you sure about that?” while the creator shows themselves oversleeping.

Why it keeps trending

  • The phrase is short and universal , so it works across fandoms, games, politics, or everyday life.
  • New shows and edits (like Invincible and Tim Robinson’s sketch) keep giving the line fresh visual contexts, which revives the meme for new audiences.
  • It fits current “reaction sound” culture on TikTok, where a single audio clip becomes a modular tool for thousands of different situations.

So when you see “are you sure about that meme” mentioned in late 2024–2025 discussions, people are usually talking about either the Tim Robinson reaction sound or the Invincible Omni‑Man edits, with the John Cena clip as the older, foundational classic.

TL;DR: The “are you sure about that meme” is a family of reaction clips (John Cena, Tim Robinson, Omni‑Man) used to humorously question someone’s confidence or correctness, especially in TikTok and edit culture.
