amfho

To disregard/abandon/ditch a person or other entity. The word is actually an acronym for "a man for his own".

Origins of the term:
"Amfho" which came about one sweltering afternoon in Kuala Lumpur, Malaysia.

A Muslim dude (a bit wasted at the end of a hot day in the holy Muslim month of Ramadhan, while he was fasting) was responding to his Christian friend who offered to fast with him as a show of support. He replied "nah don't worry about it, a man for his own" (where he had inavertently spliced together "every man for himself" and "unto each his own", and mutated the first word).

The term amfho subsequently achieved a great deal of popularity in Sunway College, and it has now been exported to the rest of the world, most notably Australia.
