Haha There is also another technique we practice in Brazilian Jui-Jitsu where you meet the attackers aggression by moving forward to hug him. It's called a "clench" but it looks just like a "hug". The reason you hug him is similiar to western boxing where one boxer hugs to prevent the other boxer from being able to hit him because of the distance. They call Jui-Jitsu the gentle art for a reason I guess :) One interesting fact is that the technique does not work if you are moving backwards, and its important that you are going towards him. There is a leading step kick that is just a feint so that you can get closer hehe.
