DATR
Means "Dib and Tak Romance". Used to describe the pairing, often in Fan Fiction, of Dib and Tak, the characters from the popular television show Invader Zim. TADR is also used.
I was reading pages from an Invader Zim fan fiction, but was immediately turned off when I heard it was a DATR

See that couple over there? The datred between them is palpable.
