The 'Vector Hey' meme stems from the 2010 animated film Despicable Me, featuring the eccentric villain Vector. The template captures a specific moment where Vector, dressed in his signature orange warm-up suit, leans into the frame with a smug and unsettlingly calm 'Hey.' It became a viral sensation as a reaction image used to represent unwanted visitors, intrusive thoughts, or a persistent problem that refuses to be ignored. Its popularity skyrocketed on social media platforms because it perfectly encapsulates the feeling of being confronted by something slightly annoying yet unavoidable.
