n. A refreshingly warm beverage derived from an individual suffering from an extreme case of diarrhea (either naturally or chemically induced). The person producing the frothy mocha latte (FML) must first be anally inseminated before shitting into a coffee mug and serving it to another person.
Whipped cream is permissible as a topping only when the person drinking the FML is actually aware that they have been handed an FML. The FML doubles as both a sick, sexual fetish-type drink and a hell of a good way to exact revenge on a friend.
"man, you gotta try my frothy mocha latte"
"yeah, dude. give me a taste... oh, man. that kinda tastes like shit"
