The 'Copy That' meme refers to the military and radio slang used to confirm that a message has been received and understood. In internet culture, it is frequently used to depict characters—often soldiers, pilots, or even cartoon characters like Peter Griffin—acknowledging an absurd or mundane command with professional stoicism. It gained significant traction as a reaction image for situations where someone blindly follows instructions or sarcastically agrees to a ridiculous demand. The humor typically stems from the contrast between the high-stakes terminology of tactical operations and the low-stakes or nonsensical context of the caption, making it a staple for office humor and gaming communities alike.
