What is "pescozada"

Pescozada is a hip-hop group formed in Chalatenango, El Salvador. They usually rap in Spanish, sometimes throwing in bits of English like "Yeah" "Uh-huh" or "Hip hop", and use an extreme amount of Caliche. Their name, which used to refer to an honor given to a knight by royalty, literally means "slap" or "punch" (usually in the face) in modern Spanish. They are also well known throughout El Salvador for rapping about topics like the country's political situation, its problems, and its civil war.
