Manspreading, or man-sitting, is the practice of sitting in public transport with legs wide apart, thereby covering more than one seat. Both this posture and usage of the term "manspreading" have caused some internet criticism, and debates in the USA, UK, Turkey, and Canada. The term first appeared in public debate when a feminist anti-manspreading campaign was started on the social media website Tumblr in 2013. The Oxford English Dictionary added it as a word in August 201: The practice whereby a man, especially one travelling on public transport, adopts a sitting position with his legs wide apart, in such a way as to encroach on an adjacent seat or seats:

a campaign to discourage manspreading or using an adjacent seat as a footrest.
