Munky Juice is a fictional beverage featured in Grand Theft Auto: San Andreas and Grand Theft Auto: Liberty City Stories. While unavailable for consumption to the player, posters promoting the product can be seen in Grand Theft Auto: San Andreas inside 24/7 shops. The advertisement depicts a monkey hanging on another monkey's testicles. The same advertisement can be found plastered onto a wall in Bedford Point, Staunton Island in Grand Theft Auto: Liberty City Stories.
- The product appears to be based on Um Bongo, a popular fruit juice drink in the United Kingdom.
- Munky Juice may refer to semen, with "munky" being close to "spunky", which is slang for semen.
- The slogan "freshly squeezed taste of parasites" may refer to sexual diseases (taste of parasites). "freshly squeezed" may also be slang referring to semen after masturbation.
- Orang-O-Tang, GTA IV equivalent.
