Kieren Lee-Murphy's definitions

hfdym

An abbreviation that translates as "how fucking dare you mate". It is not an acronym, and each letter is pronounced. Accordingly, it reads "H-F-D-Y-M".

Increasingly used in Australia between friends to express disdain or amazement. Used in a tongue-in-cheek or friendly manner.
