Bloodlust or bloodthirstiness refers to a desire to see blood being shed; although it is a portmanteau of blood and either lust or thirst, it usually refers to a desire to see blood being shed in combat (which the heroic bloodshed genre in popular culture follows, with modern examples such as Purgatori, Bloodrayne, and films directed by Quentin Tarantino.)
It can also refer to a literal lust or desire, for either the sight or drinking of blood, such as blood fetish associated with sexual activity, or for drinking blood in vampire-like behaviour similar to vampire myths.
