When a rich kid is attracted to unattractive chicks with no ass and no tits. Taking diffrent ugly chicks down to his basement nightly and screwing them on the already-broken couch that his older brother broke a night prior from screwing a fat chick.
dammit dude! Keep it quiet downstairs. All of Glennmora will hear you if you don't stop givin that chick a B-Lane!
An inconsiderate fucktard who upon attaining the leftmost lane on an interstate will not get out of the lane to let faster traffic pass by. Such an individual typically believes that since they are doing the speed limit or slightly over, no one else should be able to go faster since they would be breaking the law.
Bill was driving like an eighty year old woman in the left lane. He had thirty cars waiting to get by, but he would not get over because he was a Left Lane Bandit.
Used by students at the University of Texas in Austin when their homework/studying keeps them up so late that Kerby Lane, a 24-hour restaurant, is the only good place open at which to eat. Only to be used in extremely stressful situations, like having to write a six page paper the night before two midterms.
The expression in no way implies Kerby Lane is itself bad. In fact, it's awesome, especially the pancakes and signature queso.
Student 1: Oh my god, I have so much work to do tonight. I'm going to be up until 4am.
