The best way to draw burps in vore?

[157and493]

A friend of mine was working on a request for me recently but he told me that he was not satisfied with how the burp sound effect looked no matter what he did. This got me to wonder, which way do most people prefer to see burp sound effects depicted in vore? As a word bubble with the phrase “burp” in it, as a gas cloud, or as just letters in the air, or something else?
Burping is an essential element in vore to me so I am curious as to what the general consensus is.

I think the main thing is a good expression on the pred. Either eyes wide or crossed in surprise or half closed in nonchalance with the lips splayed out as the belch blows out past them. I'd say a few letters in the air is usually enough but some bits of the prey coming out can help sell it.

Any method to approach on burps will work good, I personally enjoy clouds and noises too.
