look up any word, like cunt:
 
1.
An acronym for Zim and Tak romance, used in INVADER ZIM fanfiction and fanart to describe a (virtually impossible) romance between, Zim and Tak, uh DUH. Most fanfiction in this catagory is written by fangirls/boys who aren't into Xenophilia, but want Zim to find love. Enter Tak. There are few actually GOOD ZATR fics out there, but they DO exist.
Fangirl#1: That ZATR was so BAD and OOC that I was about to puke!

Fangirl#2: I KNOW! I mean, REALLY! She HATED him eairlier, but now she realizes she LOVES HIM?!?!?!?! IRKENS CAN'T LOVE!!!!

Random ZaDR fanboy: YES THEY CAN!!!!! ZADR ALL THE WAY, BAYBEH!!!
