Abnormous: irregular; exaggerated; misshapen; enormous. 

This is an old word, one that has dropped out of use.  What a shame.  Let’s bring it back. 

Here’s a start: “Stop pulling me down with your abnormously negative attitude.”

Abnormous is a combination of abnormal, and enormous.  Both abnormal and enormous derive from the same Latin root.  Norma, in Latin, is a carpenter’s square; a standard, a pattern.  Something ab norma is removed from the standard.  Something e norma is outside of the standard.
