For those interested, the man in this video,
Is selling burping videos. He is very easy to work with and very able to pump out massive belches for as long as you need him to. Some of his burps were over 5 seconds and they were super loud. He has also put on more muscle mass since this video, which was a few years ago.
For those interested, PM me, I will give you his number so you can talk with him directly.
Sorry for those that wanted me to post here directly, it’s his Whatsapp so I’m trying to be a bit careful.
