A young woman who has had sexual relations with 3 or more brothers of theta chi fraternity. Called so because the Greek letters Theta and Chi resemble the word "ox" in English, while "box" refers to the young lady's now-worn-out vagina. Hence, the "OX" is in the "box".
Is she an ox in the box now?

No, he didn't break the plane.
