A college student who lives in a dorm building and spends a great deal of time in the halls of that building, especially after the majority of their fellow resident students have gone to bed.
I couldn't sleep last night because the hall rats were up talking.
I could hear the hall rats discussing philosophy late into the night on my hall.
I tried to go the bathroom in the middle of the night and almost tripped over a hall rat.
