When a man suffers from a minor illness, typically a cold, but complains of severe symptoms, such as severe pain and nausea, they are said to be suffering from man flu. Lots of men tend to exaggerate their symptoms when they have a minor illness.

一位男士身体微恙时，比如他感冒了，就会不断抱怨症状有多严重，又是疼痛、又是恶心的，我们就说这位男士患的是man flu（男士感冒）。很多男人稍微得点小病就会把症状说得很夸张。

The female perspective is typically that the afflicted man is suffering from attention-seeking behavior, or that men have a lower pain threshold. The male perspective is that actually it does hurt and he needs more care.

从女性角度来看，患病男士其实是在寻求更多关注，或者男士对疼痛的耐受度比较低。而在男士看来，这病的确让自己很难受，需要得到更多关爱。
