How many of us use the expression, 'Like a Girl" as a put down maybe without really meaning to hurt ?

The other day I was playing golf with three other guys and one guy said he was 'playing like a girl'.

Now no harm was done in that moment among us guys, or was there? If the thought is in the back of our mind, what's to stop us from saying it again around our daughters and ingraining them with a feeling of 'less than'. Watch this video and see if you agree.
