I have
NEVAH burped out loud I'll have you know.......that would be incredibly rude and soooo unladylike.
I can hear everyones eyes rolling in their heads!! Yes, I have burped out loud when alone but usually don't say anything unless it's to one of the cats....and they don't care one way or the other. They're butt-sniffers so I don't think they can be offended.
Now...if I were to do it in front of one of my boys that would be something they'd never let me forget or live down!!
