A person that goes to a bar 5 to 7 times per week yet is not an alcoholic. Also hardly ever works 40 hrs / week yet complains of never having money and goes to counseling for depression, mainly caused by lack of money.
That bar rat only worked 10 hours this week, had to miss a half day of work for counseling, has creditors calling everyday, yet is going to party at the bar tonight... WTF!

Most commonly referred to for girls, going downtown to the bars every week. If they become a regular at the bars, there definitly a rat. once a week is still considered a rat, just gets worse if they're there more.
That bitch is at the bar more then she's with her man, what a bar rat.
