God help you on the first day he has something like Taco Bell....some things can never be unseen.

That's a new one lol

Reminding anyone else of the How I Met Your Mother episode referencing a similar tradition?

So now it's your turn to retaliate. Take a picture of your poop and then send it to him while he's eating dinner

This is a somewhat common phenomenon. My brother and his friends do it. They call it "shexting." He even has a date and time log of every one he takes. No pun intended.

If you're a woman, send him pictures of your monthly womanly bodily excretions.

I don't know what kind of phone you have, op, but if it's a smart phone, go into your settings in your text messaging, and make sure you go to multimedia message settings. Make sure you aren't auto-retrieving those messages. That way, you have the option whether or not to actually see his messages. I don't know if you can do this or something similar to this in any phone that's not an android. But if you can change your settings, just tell your brother he can send all the "crap" he wants, and that you aren't going to see any of it. If I were you, I'd tell him not to expect that I'll see anything important that he wants me to, because I've filtered his "crap" out. If you can't filter him, sorry Op. I seriously gotta wonder about your brother's maturity level.

Your brother is deranged.

I hope you're a gastroenterologist, and not Dirty Sanchez himself.

im pretty sure pictures of poop are considered modern art these days. but only if taken with instagram.
