Someone of humble origins, new to the middle class who makes a big deal about food shopping at Waitrose or M&S. Such types will lose no opportunity to let you know where that "delightful couscous salad" came from and will frequently carry other items in a Waitrose/M&S bag to drive the point home. Normally the dregs of society who get their news from The Daily Mail, they will often scorn Aldi/Lidl shoppers and invite others to share their disgustinginsecurity. Regard themselves as "posh", a word and a concept that is alien to anyone with breeding.
That Chavrose was around again this morning, banging on about who came to her dinner party.
Oh God, that awful Chavrose is coming over. I've never met anyone so common.
Akin to the seemingly antiquated phrase "Get a room," "Get a Chatroom" should be used openly towards couples, or anyone for that matter, getting a bit too mushy online. Perfect for facebook wall conversations. It can also be used for when your notifications get bombarded because you decided to say "Nice Outfit!" on a friend's picture. This picture then sparked a flirtfest between the picture-poster and another random individual, leaving you to not only get annoyed, but notified! Next time you see this retch-inducing display online, let them know what they should do!
