foochila:

used to describe a very bad smelling oder. Also often used by mothers with infant babies. After the mother discovers the baby(s) have shit themselves, they immediately make a cringing, sour face and say the word "foochila" while waving their hand in front of their nose.
OMG, did you smell that ? "FOOCHILA" !
