A portmanteau formed using the first two letters of the words: FAce DOwn ASs UP and describes the way a person (frequently the person that will be the passive or receiver in anal sex) has positioned their body while awaiting a pending sexual encounter.
Craig was in his bedroom fadoasup awaiting the arrival of Larry, Todd, Emile, and Jarjar who would no doubt desecrate his anus.
