意思你: 你的心思不在一个地方 这个词指感情. 用情不专一. 对待感情不认真

it means 'you are a playboy'. you often keep several relationships with girls at the same time. aren't you? haha...

slang phrase for "have more than one relationship at a time"

脚踏数条船=花心 if you have more than one girlfriend, It will be suitable to use this word to describe you. 常常= always

脚踏数条船 = a person are seeing someone else while he or she already got girlfriend or boyfriend. I don't agree with what Wind said, I think it doesn't mean "have sex with more than one person". It depends, in part, on what kind of person he/she is . Just like someone like flirting with girls and maybe will make out on the couch with those girls. If your friend are kidding by saying "你常常脚踏两只船？ "，then you can say what ever you want to say. But if your girlfriend ask you like that and you say "yes"， I think your girlfriend probably will break up with you, yelling “Get out of here”.
