File:Not that way.jpg
An initialism, short for "NOT THAT WAY" (all-caps required), as in, I love you, but NTW.

The full acronym, as made by Brackets, is ILYNTW (I love you- NOT THAT WAY).

Origin Edit

First appearing amongst the yadas on the thirteenth of September as used by our Lordyada P, in response to a comment which said, "Anamia, I may be interpreting this incorrectly, but I believe the reference to the insults conversation was just P's way of telling you he loves you," to which he replied, "yes. but just NOT THAT WAY.").
