look up any word, like cunt:
A lime that only ~1/8th is used and the rest goes to waste. Usually for the sole purpose of making a cocktail or garnish.
Wife: "I am tired of throwing out the sacrificial lime every Sunday."

Husband: "I guess I should start drinking more and use the whole lime."

Wife: "Or you could not act like such a pussy and drink your Jack and Diet Coke without one."
