The Slug

A slug is like a teaser that summarizes a show. Not typically used in anything other than news TV and radio, but occasionally seen in entertainment. Example:

""Flooding has claimed three lives in anywhereville, please tune in for details"."

For syndicated shows, the slug may be a short episode synopsis that the local station gets in the syndication deal. The local station will tack on a card at the end showing the time the show will run. Example:

"Syndication Voiceover: "Hilarity Ensues as Bobby gets a new pet!"

Bobby:" "Mom look what I got!" (canned laughter)

Syndication Voiceover: "On the next Show X!"

Local Voiceover: "Tonight at 5 on Station X!""

Websites, news and blogs in particular, use a slug for a mnemonic URL for content. For example this exact TVTropes page's slug is TheSlug.
