sic 

(sic) (Latin for "thus") is a bracketed expression used to indicate that an unusual spelling, phrase, or any other preceding quoted material is intended to be read or printed exactly as shown (rather than being an error) and should not be corrected. When found in a French document, (sic) stands for "Sans Intention Comique" (without comic intention) meaning that even if the preceding text could be understood as funny, it was not meant to be. It is used by writers quoting someone to alert the reader to the fact that an error or other weirdness in the quoted material is in the original, and not an error of transcription. "Sic" is almost always enclosed in parentheses.

A simple way to remember what it means is to consider sic as a pnemonic for 'spelt in context'.

*sic* 

Latin, "thus"; used to indicate that an error in the original has been replicated in a quote.

When you're quoting someone else, and the original includes an error (spelling, fact, conception) it may be necessary to assure readers that (a) you noticed the error and (b) it is not yours, but that of the person you're quoting. Since it is a Latin expression, it needs to be italicized, and in the Urban Dictionary this means enclosing it in asterisks.

His columns are full of brilliant insights such as this one:

"World War II erupted at Munich *sic* in 1941 *sic* because President Roosevelt *sic* was too weak-kneed to stand up to Hilter *sic*."

The man should not be allowed to go about unattended, let alone publish newspaper columns.
