To be annoying, stupid, etc. Lumpatious is usually used as an insult to someone who thinks they are the best thing since sliced bread.

From the tv show Sam and Cat, lumpatious is used as an insult. Since Cat uses it, it is not a bad insult. It means to me to be a lumpy potato-like thing.
New Jeresy, don't be Lumpatious!
