A person that's known for a
meme that they made/are in, and are only known for that
meme. Sometimes they either accept it and move on with their life, or try and make some profit out of it before it gets old and some even make a decent sized platform out of it, but some can sometimes be annoying as
hell and drag that meme for years.
