A "googolplex" is 10googol , i.e. a googol of zeroes as the exponent. This is larger than the estimated number of atomic particles in the known universe.
There is a proposed Greek naming system that would supplant these US and the competing European system (counting by millions).

one vigintillion
A vigintillion is nothing but after a digit if there are 62 zeros it becomes a vigintillion like after a digit if there are seven zeros it is a crore.
sextillion neptillion
Oh, dude, a vigintillion is like a huge number already, right? So, something bigger than that would be... well, a googol! Yeah, like a one followed by a hundred zeros. It's like the ultimate mic drop of numbers, you know? So, if you ever need to impress someone with a big number, just drop a googol on them.
A vigintillion is represented in short scale (American and modern British) usage as 1 followed by 63 zeroes, while it is represented in long scale (continental European and traditional British) usage as 1 followed by 120 zeroes.

Vigintillion, and yes that is a number.

A "zillion" isn't a real number-name. However, you're probably thinking of a vigintillion, which is 1 followed by 63 zeroes.
In short scale, common in United States and modern British usage, a vigintillion is 1 followed by 63 zeroes. In long scale, common in continental Europe and older English usage, a vigintillion is 1 followed by 120 zeroes.

A: "bicentillion" doesn't exist, I think you mean: centillion, or here in Britan a vigintillion, a vigintillion has 120 zeros after it and a centillion has 303 zeros after it.
The correct spelling of the large number is vigintillion(1 x 1063 short scale, 10120 long scale, e.g. in Europe).
