mouse理解成“鼠标”，mouse potato天天握着鼠标的土豆，不就是“电脑迷、整天趴电脑前的胖子、沉迷网络无法自拔的人”。

【例句】
First, my husband became a coach potato, and now my son is becoming a mouse potato.
我的丈夫先成了一个电视迷，现在我的儿子又成了一个电脑迷。

When my mother learned how to use the Internet on our home computer my father complained that she had become a mouse potato.
当妈妈学会在家里的电脑上使用互联网后，我爸爸抱怨说她已经变成了网虫。
