自作多情二逼廖汉
[zì zuò duō qíng èr bī liào hàn]
This username translates to 'Self-proclaimed affectionate silly Liao Han.' It's a humorous and somewhat self-deprecating way of identifying oneself. The term “二逼” (erbi) is slang for someone who behaves in a silly or stupid way. The person might be using this nickname in a lighthearted, mocking manner about themselves.
