Crunk is a sub-genre of hip hop music that started in the clubs of Memphis, Tennessee in the mid-1990s. The word 'crunk' is the past tense version of the word 'crank' as in "crank the music up". It can also be used as an adjective. It is a mixture of Miami bass, Southern rap, and electronica with a lot of yelling and chanting. Lil Jon is the most popular crunk artist, and his song 'Get Low' with the Ying Yang Twins is the song that made crunk music mainstream. After this song came out, crunk became a really popular style of music and it saw it's heyday in the mid-2000s, but it eventually started to fade away and disappear, being replaced with trap music in the 2010s.
