我杯茶

I am just a cup of tea (slang expression): In a very humorous and casual context, it refers to oneself as something insignificant or unimportant, sometimes even disposable, just as one might view tea served merely as a matter of course or routine rather than something of value. In other contexts, it can also mean enjoying oneself at ease or taking life simply and calmly, like leisurely sipping a cup of tea.
