athetits means: -noun 1. The corruption of the word “atheist”, which was probably first seen on Yahoo Answer Citation needed. Although the source of this word’s origin is not clear, it was likely created by some “n00b creationtits” who accidentally mispelled the term “atheist”, creating failmeme. It is used now, only on RS board as a joke or insult to atheists. This word can be used in both the singular and plural. However, if someone has one tit then you should call them athetit.
