Most Helpful Guy
Burping on command. And not just the "uuuuph" thing like most people do. I puff out my cheeks and compress air into my mouth, then i allow my stomach to unsettle itself and then i force it out. My average burp is as loud as a drum beat, and lasts for 30 or so seconds of solid burping.
Not sure if I'm proud of it or not...1
