OMGJK 

Oh My God, Just Kidding (OMGJK) - A situation when you find something to be so preposterous or unexpected that it raises a sense exclamation, but during the climax of that emotion, you find the opposite to be true, thus negating any original feeling of excitement.

Example 1: When a friend tells you that she's bringing an extra person on a ski trip causing you to upgrade your rental car (OMG); then tells you that the extra person has her own car and that your friend is riding w/ her, causing you to downgrade your car (JK); then tells you she wants to convince the extra person to come in the rental car because it's "funner," which would require you to upgrade your rental car (OMG); then tells you she failed to convince the extra person to ride in the rental car, thus negating the need to upgrade the rental (JK); then tells you the extra person is no longer coming so your friend will need a ride, causing you to upgrade your rental (OMG); then tells you the extra person is coming again and your friend is riding with her, causing you to again downgrade your car (JK).

-To avoid the lengthy description above, this situation may simply be referred to as OMGJK, OMGJK, OMGJK, or just OMGJK for short.

Example 2: When a beautiful girl 3 notches above your league walks over and tells you she thinks you're "hot" (OMG) then you see her laughing to her friend as she walks away (JK).
