"Mosuckra" (Ebonics/English): The pathological labeling of a comically inferior person in one or more areas. Commonly associated with the African-American slang of the word "Motherf***er", "Mofo"; carrying an alternate, less abrasive meaning as in the word "Mothersucker". Not a universally recognized word, "Mosuckra" has since been assumed the spiritual "Mofo" to "Mothersucker".

Originally used by Youtube comedian and celebrity Toby "Tobuscus" Turner.
