In a high school, suspicious students (generally wearing dark emo/goth clothing) who loiter (creepily lurk) in the hallways of a highschool after school hours.
I watched disgusted as the hall-rats made it to second base in the locker bay on my way out of school.

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.
