The 'Sike Nigga You Thought' meme is a classic internet reaction image used to signal a successful deception or a 'bait and switch' prank. Rooted in urban slang where 'sike' (or psych) means to trick someone, the phrase gained massive traction on platforms like Vine, Twitter, and Reddit. It typically features a character making a mocking or celebratory face, perfectly capturing the energy of tricking someone into believing a false scenario. It is the go-to template for moments where someone is caught off guard by a sudden reversal of expectations or a false sense of security.
