Quettapenis

A word that, as of late 2022 when quetta became the official prefix for 10^30, nerds can use to say how massive their member is. 1000 times larger than a ronnapenis, and a million times larger than the yottapenis. A yottapenis is in turn 1000000000000000000000000 times larger than the regular penis.

As you can imagine, the quettapenis is an absolute MONSTER.

Its antonym is the quectopenis (10^-30).
