Manspreading is the act of a man sitting with his knees spread widely apart, particularly when this crowds people next to him or prevents someone from taking an adjacent seat.

“大爷式占座”指男性将双腿张开的坐姿，特别指他们用这种坐姿将身边拥挤的人群挤开，或阻止别人坐他们旁边的座位。

例句：

Any woman travelling by public transport will be aware of manspreading — where a male passenger sits with his legs splayed out, totally oblivious to the woman next to him who’s forced to double cross her legs for lack of space.

乘坐公共交通工具的女性都知道什么叫“大爷式占座”——男性乘客完全不顾旁边的女性，在座位上张开双腿，把旁边的女性挤得只好翘起一条腿。
