omomg 

Oh My omg (Oh My Oh My God)

Double impact of the original OMG, causes greater intensity in an already bad or good situation.
Used to sometimes describe how truly bad, or good, a situation is.

OMOMG, did you see the X Factor last night? Matt won, the prick!
OMOMG, Yeah! I can't believe Matt won! :O What a douche!
