Define Motherless Meaning

ad-swearword; used in conjunction with additional swearwords to amplify the meaning.
Implies that the subject was born of no earthly mother.

somebody totally drunk

A double insult, accusing one of having no father or mother, implying that one was simply found somewhere, possibly under a flat rock or some other place where disgusting things might be found.

An ingenious spin on the ever so versatile term "fuck." Derived from the bowels of a US Navy ship, the term literally means, well, exactly what is says: "motherless fuck." Motherless, meaning without a womb, and fuck... well, there're thousands of possibilities. A comparable term, Mother Fucker, can be used alternately when "motherless fuck" does not fit the context in a desirable fashion (though, I don't foresee many situations in which "motherless fuck" would not work...)
