There are 10 stalls in a restroom, all are empty, except the one you are in. Another person comes in, surveys the situation, decides to shit in the stall right next to you. Only 2 possible reasons. They want to smell your shit vapors and/or want you to smell theirs.
I ran into a poo snuggler at work twice this week. The smell was beyond rancid. I want to scream "Why are you shitting next to me when there are 9 other stalls open!!?"
