Literally means "Do it yourself, Mother."

Used both ironically and unironically by teenagers to denote disapproval to an assigned task given to them by a maternal figure, while also redirecting this mission to the asker as they cannot be arsed at that moment in time to do such a deed.

As is common with slang popular among younger generations, some teachers will try to appeal to the "youngsters" by picking up on this versatile phrase and use it in class as well, often to their dismay.

The interjection 'Mom!' may also be changed to any title (often shortened to one syllable) showing a relationship to the speaker such as Dad, Sis, Bro, Cuz, Dude, Girl, Boss, Boi, etc.
Mother: My feet are killing me. Could you be a doll and massage them for me?
Teen: OMG! DIY, Mom!

'Cool' Teacher: My mom asked me to go over to her house because she was feeling lonely this week, but I just told her, "DIY, Mom!" Ugh, mothers, am I right?
Class: You're such an asshole.
