21th base

When idiots or little kids try attempting to look up bases only to find that 21th isin't even a word.

*Incase you haven't figured, the correct word is 21st Base and theres no such fucking thing*

14 Year Old Boy: OMG OMG I'm so horny from reading these bases especially the Goat Sex 19th Base or whatever the hell it is.
<Types in 21th Base>
Oh...wait....21th isin't even a word I'm fucking stupid.
