An abbreviated medical term known as Leaky Bum-hole Syndrome. LBS is a disease where you may leave mysterious liquids upon the surface of chairs within minutes of sitting on them, this is due to the prefuse sweating of the rectum. The average age of diagnosis is around 16 but can come at any time.

1. (unit of measurement) the abbreviation for pounds, which is weird because the word "pound" doesn't have an "L" or a "B" in it, that's English for ya.

2. acronym for a few different phrases:

- Local Bike Shop (similar to local fish shop)

- Little Bitch Syndrome, which is a tendency to be lazy

- Laughing But Serious

A synonym for pounds. When read, you read it as pounds. Originated from the Zodiac Sign, Libra, which is a balance, or scale. That referred to weight, so people decided to substitute it for pounds.
