Madrid is banning manspreading.
The Spanish capital has become the latest city to launch a public awareness campaign asking male riders to keep their legs to themselves when sitting on the subway.
Not sure exactly what manspreading entails? In 2015, the word was officially added to the Oxford Dictionaries and is defined as: "The practice whereby a man, especially one traveling on public transport, adopts a sitting position with his legs wide part, in such way as to encroach on an adjacent seat or seats."
Following the lead of New York City, transit officials in Madrid have also boarded the offensive, posting signs on public transport this week asking gentlemen riders to be respectful of others and refrain from taking up more than one seat unnecessarily.
The new signage is part is a wider etiquette campaign, which also reminds riders to refrain from putting their feet up on the seat, eat or drink in the train, to use headphones with portable devices, and to give up seats to the elderly, riders with babies, and the handicapped.
What started as a shaming campaign on social media in New York a few years ago became adopted as an official public service reminder on the city's public transit system in 2014, with signage that read, "Dude...stop the spread please. It's a space issue."
Before that, Paris had also launched a set of metro-riding etiquette guidelines called the 12 commandments, which reminded riders to be courteous, carry heavy bags for elderly riders, and be mindful of the volume of their music and phone conversations.
