British Oxygen Company. Although they provide just about every other gas and also liquid oxygen and liquid helium.
I was going to use the cryostat today but there was no liquid nitrogen. Oh well, BOC make a delivery tomorrow and there'll be enough left over to freeze some rats.

We use BOC to describe a particularly whorish girl, or a desperately idiotic guy. You can figure out for yourself what the "balls" are and how they could end up on someone's chin. ; )

Balls On Chin - When I guy or girl is giving a BJ, and continuously goes full shaft. The position of the BJ recipient's balls will often slap or rest on the chin of the giver. Depending on the relationship, this can be harmless, almost like a love pat, or it can create an irritation to the chin of the giver.
- Hey did you see that chicks chin?
- No did she have a big zit on it?
- No it looks like she fell and scraped it all up?
- Oh that, yah I did see that, I bet she got her some BOC last night.
