Etad
An etad (pronounced e-tad) is an ambiguous encounter between two people that may or may not be a date. The word, derived from the spelling of "date" backwards, is typically used when one or both parties is/are uncertain whether the scheduled time together is a date, or how the other would classify it.
I think I'm interested in him, but I'm not sure if we're hanging out as friends tonight or if it's an actual date. I guess it's an etad.
