I don’t understand the joke

Cold jokes generally make a certain mockery of society~

On the surface, it can indeed be understood that the side effects are the speed of a snail~ but further it can be said that it is the habit of a snail- -Hiding in the shell (home)~

The huge pressure in today's society makes some people feel that once they leave the house, it is like a snail leaving its shell~exposed to the broad daylight~without any safety Feeling~

I think its meaning should be to satirize the pressure that society brings to people or to satirize those otakus and otakus who cannot adapt to the current society~
