The Gers. Like many of the best nicknames, Rangers' most popular moniker comes from a simple shortening of their name. Ironically, fans often refer to the club as 'Glasgow Rangers', although the city in which they play has never formed part of their name officially.
The nickname Teddy Bears became popular during 1970s, inspired by Cockney rhyming slang. If one were to imitate a thick Glasgow accent, Bears will sound like Bers and that then rhymes with the word Gers - a shortened version of Rangers.
