Dastardly

[Tanya Shivari]

Strangely, bastardly is not a word, but the same meaning is served by the term dastardly. Once a serious insult, dastardly is now almost always used [sarcastic]ally. If used seriously, the speaker is most likely a [nancy boy] and/or [fop]. It is generally used in the phrase dastardly deed(s).
