Lamazep
LamazeP (ラマーズP) is the creator of three famous internet memes: "Get Down", "Po Pi Po" and "Fukkireta", the latter of which he composed himself. Many of his works are cute and silly, but he has created some serious songs as well. He is known to have used the producer name GojimajiP (ゴジマジP), but it is still unclear if LamazeP and Gojimaji-P are two different people.
He is also very skilled at art, and many of his videos feature his own illustrations.
