noun an African melon
noun large oblong or roundish melon with a hard green rind and sweet watery red or occasionally yellowish pulp
originFrom the 1610s, a compound of water + melon. Compare French melon d'eau, German Wassermelone, and Spanish melón de agua. The meanings referring to environmentalists and behind-schedule projects derive from the idea of having a green (eco-friendly, on-schedule) outward appearance while being red (socialist, behind schedule) in a hidden way comparable to that of the fruit.
