Swag其实是Swagger的简写，原本的字面意思是“自大、骄傲”和“strut”是近义词。后来慢慢转变成表示“酷、有腔调（cool or smooth, or awesome 酷，棒 ）”。例如：Wow, your life sounds so swag! 你的生活真的好酷噢！
Swagger更好的表达是：to walk with an air of overbearing self-confidence神气十足(地走)，大摇大摆
Eg. He walked with something of a swagger.他趾高气扬地走着。
Don't ruin my swag.不要破坏我的造型！
但是swag这个词其实现在已经不潮了，在国外是五六年前流行的词汇。
It's now UNCOOL to use the word. This word was popular maybe like 5 or 6 years ago. But now it was so overly used that it's now NOT COOL to use it ONLY unless you're making fun of someone or using it sarcastically. 现在这个词已经不潮了。这个词大概在五六年前流行。但因为被使用过多，现在已经过时了。所以现在一般我们只在讽刺人的时候用。
