portmanteau有混血的意思（字典找不到）？还是一种修辞？

& F1 c8 B! R* |4 g: g
4 P& g, e- E' q“I do regret it,” the rapper Rich Chigga said, of his stage name, as he sat in a smoky greenroom backstage at a club in Manhattan. Chigga, a seventeen-year-old Internet star, was born and raised in Jakarta but is of Chinese descent, hence the portmanteau.

按照上下文理解，这里的portmanteau就是混血的意思，但是在字典里没有这个解释。

所以portmanteau有一个特殊的含义字典没有，还是这里是某种修辞手法？
