Meaning of “Otsu(おつ / 乙)”

This article was written over a year ago.

Basically, It means “Thank you for your hard work.” or “You did a great job.”.
“Otsu(おつ)” is an abbreviation for “Otsukaresama(お疲れ様)” and this is a slang.

Otsu(おつ) have two meanings.

One means “Thank you for your hard work”.
We use “Otsu” when we want to thank someone for his/her great work.
(This is a slang so it’s too frank to use against elderly people)

The other means “Thank you for your ‘stupid’ work”.
In this case, “Otsu” is a sarcasm.
