A tomar por culo is a common vulgar Spanish expression used to dismiss someone or something, roughly equivalent to telling it to go away in the strongest terms. Split as atomarporculo online, the phrase circulates as a short reaction audio on soundboards and in chats, edits and gaming clips. Its popularity comes from how quickly it communicates total rejection without needing context, and the clipped shout works even for viewers who do not speak Spanish because the tone makes the intention completely clear.
