Mamil (or MAMIL) is an acronym and a pejorative term for a "middle-aged man in lycra" – that is, men who ride an expensive racing bicycle for leisure, while wearing body-hugging jerseys and bicycle shorts. The word was reportedly coined by British marketing research firm Mintel in 2010. It gained further popularity in the United Kingdom with the success of Bradley Wiggins in the 2012 Tour de France and at the 2012 Summer Olympics, held in London. The British UCI World Championships victories in recent years have also spurred interest in cycling in the UK.
