Commonly used in Northern Ireland for when something bad happens to a person, can be used in a joking manner or serious all depending on how you empasise the words. For extreme cases of misfortune a swear word should be added to the end.
Originally from internationally renowned homosexual "GarethSutton"'s popular expression "Yo Dee". It was used in the albeit derogatory context of attracting the attention of passing australians; but now, a bastardization has emerged in the form of "Yo Gee".
Guy: YO GEE!!!!!!!!!!!
Gee: MOOVVEEEMEEENNTT!! AAARGRGHH!! YO DEE!
A phrase used to express surprise, similar to OMG, but usually uttered without closing one's mouth, or typed without being spoke out loud to hear how ridiculous it sounds.
