What does mall rats mean?

Someone disguised as an Emirati killed an American teacher in the bathroom of a shopping mall. The next morning, Judy shouted that there was a rat in the nursery and therefore forgot to tell her the wonderful news. The figure enters the elevator and is then seen leaving the mall quickly, with a black cloth waving behind her. I was here recently and no one answered my call, although I could hear that typewriter making noise, that, that all the time.

He had repeated three times the statement that the cat was lying on the rug and the rat was coming in three times. This Eye Pawn may have been a rat, but even a cornered rat will fight with the courage of a lion.
