Feelin' yourself refers to the state of having a sense of self-confidence. You are so pleased with the way you look that you would like to show it through everyday actions. What's more, you assume that others would think the same way. Feelin' yourself指很有自信的一種狀態(tài),。你對自己的外貌非常滿意,，所以會在日常的行為中充分展示。而且,，你覺得別人也是這么看你的,。這大概就是我們平時所說的“自戀”吧？
For example:
A:"I look so good!"
A: 我看上去美極了,！
B:"you need to chill. You are feelin' yourself way too much.
B: 你還是冷靜一下吧,，你這也太自戀了。
