碍碍碍碍死你
[ài ài ài ài sĭ nĭ]
This username 'Getaistaini' sounds teasing and a bit stubborn in Chinese, literally translated to 'block, block, block till you die'. It is often used as an affectionate nickname among close friends. However, it might be too direct for foreigners as it implies someone being stubborn or difficult to handle.
