To take a steamy dump while ejaculating on someone, mostly a figurative expression although there have been documented cases of "ookage". Used to describe complete ownage of another individual.
The past tense of ok, to get oked or okayed. It means the other person does not give a shit about what you just said.
Girl: "I should probably go to sleep"
Boy: "I love you"
Girl: "Ok"
Boy: "hEy sAy iT bACk!"
Girl: "Ok *sniffs* "
Boy: "Are you crying?"
Girl: "Ok"
Boy: "Baby are you crying?"
Girl: "Ok"
This means you got oked, you should probably consider a different relationship. Maybe even consider a divorce
