What is the meaning of "shout observations"?

The women who sold their bodies at bargain prices until dawn moved around the house after eleven in the morning, when the heat from the stained glass became unbearable, and they were obliged to live their domestic life walking naked through the house while they shouted observations on the night's adventures.

I cannot make sense of the part saying "...shouted observations on the night's adventures". What does it mean for one to shout observations?

I looked up the verb shout which basically means:

to cry aloud and say something

and observation which means:

process of watching something or something that is being watched.

So, what I conclude of "shout observations" is that they described scenes of lovemaking at night by shouting. Am I correct?

You are considering only one of the meanings of the word 'observation'.

Among other meanings is:

a remark, comment, or statement based on what one has noticed or observed.

Given that definition the meaning of the quote should be obvious. The statements or remarks were shouted to one another.
