The poor, little guy. I hope he felt better afterwards and not too much ashamed.

Scaled response

Burping in public is excusable (if asked). Farting in public lowers ones standing. Throwing up in public when not drunk is your own affair. Having some kind of total bodily breakdown elicits sympathy. So if you really need to let loose go ahead but be sure to boot the moon and throw up, cry, bleed from the nose, and scream in tongues at the same time. Evacuating in your trousers, if you can manage it, will also only increase the amount of kind feelings you generate. I have never thrown up in public but I have been thrown up on in public, that is much worse.

Still my favorite vomit scene:

Praise the boy for his courage!

What about Mr Creosote?

The vomiter

The vomiter sounds as a nice title. I don't know in which country it would fit best.

Poor lad, has he eaten yet?

There isn't diabetes in his family, I hope.

There is nothing shameful about vomiting, especially not in a restaurant.

@Oscar
Upper class vomit, indeed!

Vomitee

Recently I heard (again) that in ancient times people had a vomitorium, where they could eat and eat and eat and then throw up to start eating all over again. Very inspiring if you plan on developing an eating disorder.
I remember one time when I threw up in public. I think I was six or seven years old and visited a museum with my mum. After seeing several devices for torture and lots of other old stuff that smelled like death, I wanted to get out of the place. But my mum wouldn't let me so instead I let the food in my stomach get out.

Hmm... that's too bad.
But still the Romans threw up a lot, only they didn't necessarily use the vomitorium for it... I really need to start checking my sources...

"The Romans weren't shy about vomiting, and they had vomitoria--but they didn't do the former in the latter."
