Noun referring to a Mexican rice-based drink that's traditionally served over ice, especially in taquerias. This version requires a massive dump in the recipient's glass, followed by a processional, in Spanish, of "For He's a Jolly Good Fellow".
A muy bien mexican drink, very tasty. However one must be careful when drinking an Horchata, larges tend to be too much for the average stomach to handle due to the tastiness of this milky drink. Stick to a medium. Oh and also, chicks dig a man with an horchata.
