坐地鐵、公交時最怕旁邊的人不自覺，要不拿包占一個座位，要不干脆把兩腿往兩邊攤開，直接一人占兩座。這種行為在國外已經引發公開抗議，而且還有個專門的詞來描述這個行為——manspreading。

Manspreading describes the situation when a man sits with his legs wide apart on public transport encroaching on other seats, also called man-sitting. Those who do so are known as manspreaders.
Manspreading，也叫man-sitting，指男士在乘坐公共交通工具時，雙腿向兩邊攤開，以至于侵占了旁邊的座位，我們稱之為“大爺式占座”。做出這種行為的人可以稱為“占座大爺”。

'Manspreading' has caused some internet criticism and debates in the USA, UK, Turkey and Canada. Campaigners have criticized the practice for being rude and inconsiderate to other passengers who have to stand.
“大爺式占座”行為已經在美國、英國、土耳其以及加拿大等國引發了網絡論戰和批評。反對人士認為這一行為無禮，并且沒有顧及到周圍站著沒有座位的其他乘客。
