It's one of the most annoying, most unrespectful, most dispicable thing to do. I dont care if you're dying, I don't care, whatsoever, you can hold it in, or at least release the air without producing any UGLY sounds!
Yes, I admit, it's my biggest pet peeve! Especially, when I'm eating or drinking!! I feel like vomiting, when I hear that gigantic ball of air leaving the body in that ugly way!!
I know guys do that most often, hell, they even compete in who makes the loudest sound! I really think any respectful human being is able to respect other people when they ask them not to bother them with such dirty actions.
Oh, wait, we don't have to even ask! You better know not to do it anyways!
