Mister Vin Diesel got me thinking about mix drinks and I wondered what names there may be for simple mixes (i.e. not cocktails) in various countries, so I've started this frivolous thread. To get us started....

beer & lemonade = shandy (Brit.); ? (U.S.)
beer & cola = ?
hot chocolate & rum = ?
beer & gin = dog's nose (Brit.)
juice & champagne = ?

BTW. What do the British call a cider with raspberry/berry juice?
