Egads

[Justin Bieber]

A common exclamation, abbreviated from phrases such as Ye gods!.

[PussyCat]

It is a pagan way of saying omg. It comes from the saying ye gods, and, as everyone knows, the greek and roman gods had a way of messing with peoples lives. So when you say egads, in a sense, youre saying you fuckers, but softly.
It is used to express mild dismay or frustration.

[Dianne]
