Eat my saggy - We say it because we're too lazy to think of anything better

We say it because we're too lazy to think of anything better. It’s mean, but we don’t care.

Bro, I just ate your saggy and your mom’s leftovers.

You said that to me in the lunchroom. I still got food on my shirt.

I texted him 'Eat my saggy' after he ate my pizza.
