Helium (from Greek: ἥλιος, romanized: Helios, lit. 'Sun') is a chemical element with the symbol He and atomic number 2. It is a colourless, odourless, tasteless, non-toxic, inert, monatomic gas, the first in the noble gas group in the periodic table. Helium is the second least reactive noble gas after neon, and thus the second least reactive of all elements.

It is also widely known for its effect on a person's voice, it changes the tinder and not the pitch. The effect is very similar to Hydrogen when inhaled, and you can try it yourselves! - just don't inhale too much and be in an environment where fire or electricity is involved.
Oh god! Today I tried inhaling Helium! It was extremely fun!

Used to describe a female's breasts, in most cases large breasts. This comes from the idea that the breasts are inflated, or must be inflated to reach such a size. Can be taken as offensive because it is insinuating the female in question went to unnatural means to achieve the present size of her mammaries.
That girl is straight helium; Look at the helium on that one; Lemme get that helium!
