Here are some examples:
* "I was bowled over by her kindness." This means that the person was very impressed and touched by the woman's kindness.
* "He was bowled over by the view from the mountain top." This means the person was amazed and stunned by the beautiful view.
* "She was completely bowled over by his proposal." This means the woman was surprised and delighted by the proposal.
The phrase originates from the game of cricket, where a bowler tries to knock over the batsman's wickets (pins). Being "bowled over" implies that the batsman was completely caught off guard and unable to react.
So, when you use "bowled over," you're implying that someone was so impressed or surprised that they were rendered speechless or unable to resist.
