What does Kaysa cake mean?

Kaysa cake is a swear word in Nanchang dialect, which means that this person is ignorant.

In Nanchang dialect, spreading cakes means that a person is not smart enough to speak every word, which is equivalent to not being smart enough to speak Mandarin. Gasha cake is a dirty word in Nanchang dialect, which literally means that a good cake contains sand, which makes people uncomfortable to eat. Therefore, the meaning of a gasha cake is that a person speaks without thinking and makes others sound uncomfortable.

A dirty word.

These three words are written here as "raw cake", which literally means that the cake is raw. But in Nanchang dialect, that is swearing.

Generally speaking, a person is not smart, likes to talk nonsense, talks nonsense, gets all the information from others, and thinks he is smart. We call such people "raw cakes".
