That linguistic line with the prefix [mis-](https://www.merriam-webster.com/dictionary/mis-#h2) (meaning "wrongly" or "badly") brought forth misbegotten.

In William Shakespeare's Twelfth Night, Sir Toby Belch warned Viola (who was disguised as a man) that Sir Andrew wanted to duel. "Hob, nob is his word," said Sir Toby, using "hob, nob" to mean something like "hit or miss." Sir Toby's term is probably an alteration of "hab nab," a phrase that meant "to have or not have, however it may turn out." After Shakespeare's day, hob and nob were used in the phrases "to drink hob or nob" and "to drink hobnob," which meant "to drink alternately to each other." Since "drinking hobnob" was generally done among friends, hobnob came to refer to congenial social interaction.
