Person 1: Oh, so you're an underage teenager then.
Lambert And Butler, or L&B, are an extremely good quality brand of cigarettes at a reasonable price.
They are by no means the cheapest brand, and are in fact the most popular British one, with a great flavour and a good finish.
Person 2 - Lambert And Butler dude, they're the sex!
