學個片語：＂To go bananas＂

It's an expression in English we use when we are so excited that we act almost out of control! So 'to go bananas' is not an expression about food but about behaviour. It means to behave in a very over-enthusiastic way, like you’ve gone crazy – an explosion of happiness!

I'm so happy that I finally got my promotion. Yesterday I went bananas! I ended up running around the office, hugging and kissing my boss and every single co-worker! They probably thought I was mad.

After the team scored its fourth goal in the final the fans went bananas and started to shout and jump up and down!

這跟食物無關，在英語中有不少片語，實意跟字面意有落差，容易產生困惑！瘋狂失控的行為，發瘋，焦急煩躁而情緒失控！講白點＂中猴＂（請用台語發音）！
