Omnomnibus 

Eating a week's worth of food on a Sunday morning when hungover

I was hanging, only an omnomnibus could make me feel human again

Omnominous 

When something looks really really delicious, but gives you a vague sense of foreboding.

Wow Tom, that pound of McDonald's fries covered in cheese and gravy looks super omnominous!
