This word has both a social meaning and a literal / technical meaning. Vikivortaro and Wells consider only the social meaning. The word is altogether absent in Benson and ReVo. In regard to English-English dictionaries, both meanings are considered by Merriam-Webster, but only the social meaning is considered by Wiktionary. So, the star of the show in this case is Merriam-Webster. Kudos to Merriam-Webster!
