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.
