Stupitiful
Someone who is, does, or says something so stupid, it's just pitiful.
I feel sorry for John. He tries so hard, but everything that comes out of his mouth is just stupitiful.
Stupity
A word used by the stupid to describe the stupid. It is a nearly unmentionable word; the mere presence of it speaks volumes about the author. Originated not from a typo, but from actual human error in spelling "Stupidity" in a completely incorrect manner.
LOL dude I see you like Obama he is so crazy and antichrist and Mitt Romney is good and plus he is white. WOW your stupity is through the roof, faggot.
