I'm a big guy. Generally don't do selfies for this reason exactly. It's not from one or a small group of individuals, either. I get this as a first reaction from a dozen sources a day, even strangers. I can't smile anymore.
You can't stop staring, you know you're not worthy of this magnificent booty. Still it has you under a spell you cannot break, you'll be simping and sending like the piggy you are until your balls and wallet are empty.
