先生扮可爱不是你的专利
[xiān shēng bàn kĕ ài bù shì nĭ de zhuān lì]
'Being Cute Isn't Mr. Your Exclusive Right' could be used when expressing a response to men assuming cuteness as a gender-based trait. The tone here might carry a playful challenge to stereotypes that only certain people are allowed to show this characteristic.
