你脑袋肯定被门挤过你脑袋必须被驴踢过
[nĭ năo dài kĕn dìng bèi mén jĭ guò nĭ năo dài bì xū bèi lǘ tī guò]
In a very informal and colloquial way, this is used to tease someone who says or does silly things implying 'your head must have been caught in a door' and 'you definitely got kicked by a donkey'. This is meant humorously rather than genuinely insulting though in certain contexts can come off as harsh criticism.
