脸皮太后

Translates to 'Empress with Thick Skin'. The term 'face thickness' (i.e., how shy/thick-skinned you appear to be) is often a Chinese metaphor. The title suggests the person does n't get embarrassed easily or feels confident even when others find it embarrassing. Here, by comparing the thick skin to Empress - who has great power, influence, and dignity, users show humorously they care less about social niceties and take themselves less seriously in front of criticism or mockery.
