brown texting

The act of inserting one of those fancy waterproof cell phones into the anus, and proceeding to send it text messages, thus creating a makeshift anal vibrator.

Also see "pink texting"

Example 1:
Dude 2- "Today my mom asked to borrow my waterproof cell phone. I mentioned she already had one but she demanded that she use mine. When I got it back, I noticed I was in a group chat with my mom's phone and another phone I didn't recognize. There were nothing but blank messages. I'm afraid her pink texting has escalated to simultaneous brown texting.
Dude 1- "Dude, your mom is one horny woman"
