Dangology is the science behind the "fold and tuck" that is used when McDonalds employees hand out brown paper bags of take away goods.

A good danged bag (aka 'a dang good bag') will have its corners folded down parallel to the sides of the bag, with the folded part being affected by the contents of the bag.
Official Use:

McDonalds Boss : Dang that bag!
McDonalds Employee: what? i did!?!
Boss: Dang the bag!
Employee: i already did!
Boss: DANG THE GODDAMN BAG
Employee: ok! i will! jeez!

Boss: Ok, Tim. Dangology 101 today. You ready? Set? DANG IT
*Tim dangs the bag in 2 seconds*
Boss: TOO SLOW

DANG Use:

'ARGH DANG IT! FLIPPING OPRAH STILL THINKS SHES HOT! GET A TAN!'
