Trap is a subgenre of hip hop music that originated in the Southern United States during the early 2000s. It's characterized by its aggressive lyrical content and sound, which incorporates heavy use of 808 kick drums, hi-hats, and layered synthesizers. The genre's name comes from the slang term 'trap,' which refers to a place where drugs are sold. Trap music often features themes relating to life in the 'trap,' including drug dealing and street life. Over the years, it has gained mainstream popularity and has been influential in shaping the sound of modern hip hop and pop music.
