A type of coffee so diluted by sugar, cream or milk that it no longer tastes like coffee, instead like milk and sugar, and has a beige or light brown color to it. The drink is typically concocted by those who want to appear as if they are drinking coffee but despise the taste.
Anne: Carrol is such a coffee poser, she'll only fill her mug with coffee halfway before she drowns it in milk and sugar.

Jill: Yeah, i hate the taste of her half and half and half.
