Crabcore is an internet meme that originated in 2007, mocking metalcore guitarists who squat low with their legs spread in a "crab-like" stance while performing. It has been mimicked by a variety of musical groups, leading many magazines and agencies, such as Rolling Stone, Houston Press, and NPR to classify it as a jocular musical style, or microgenre.

Attack Attack! is an American metalcore band from Westerville, Ohio, originally formed in 2005 as Ambiance, later changing their name. Attack Attack!'s first release, an independent EP titled If Guns Are Outlawed, Can We Use Swords?, was released in 2007, which led to the signing of the band to Rise Records the same year. They released three full-length albums, Someday Came Suddenly, a self-titled album, and This Means War all through Rise Records. The band left Rise Records in 2012 and disbanded the following year after a farewell tour. On October 19, 2020, the band announced a re-formation, with a mix of returning and new members.
