You probably only wanted to search something like "I dont know what" or "I dont know what to search" which lead you to this post. Realize now that you are here, in this very point in space and time. Embrace it. Then continue to question what the fuck you're still doing on this page, and why you're still reading this.

-proceeds to type out "i dont know what to search right now" and ends up on this very page, which autocompleted as "i dont know what to search right now why the fuck am I on urbandictionary" and had to be mentioned within this example because of Urban Dictionary guidelines-
