homeostupidius
A person that is so impossible to co-exist with that no combination of words can properly describe how stupid/annoying they are.
"Holy shit Devon is such a homeostupidius, he just spent 15 minutes arguing with me saying the earth is flat and wouldn't even let me finish my sentence"
"Dang he really is a homeostupidius"
"Dang he really is a homeostupidius"
