Yet another piece of internet lingo, created by combining the ever-popular "omg" with the just-as-popular-and-used "wut". There are two situations in which OMWUT can be used in:

1. Just a special, awesome version of "wut", but in response to anybody exclaiming "OMG!"

2. Also in response to "OMG!", but can also be meant sarcastically, for instance, if one is tired of another's repeated exclamations of "OMG!".
1.

PERSON 1: OMG!!!
PERSON 2: OMWUT?!?
PERSON 1: I GOT THE TICKETS!!!
PERSON 2: YAYYY!!!!

2.

PERSON 1: OMG!!!
PERSON 2: *sarcastically* OMWUT?!?
