Eructation is usually used in a scientific context. It can also be used figuratively or as a humorously technical way to refer to burping.

Aerophagia has only two sequellae: eructation or flatus. Suppress that burp at your own peril.

For lots of my friends back in the 90s, doing research into methane, or "cow farts" (despite cows mostly releasing it from their mouths), was funny. Bovine eructation aside, who's laughing now…#ClimateChange #ClimateCrisis #methane https://t.co/k0pHHJfie7

Micturition – urinating. Eructation – burping. Mastication – chewing. Parturition – delivering baby. Erudition – extensive learning.

Did you mean equitation?
