¿Qué significa 'glups?'
Usted está en el buen camino
The word 'glups' is one of those words that gets its meaning from the sound that it's intended to copy. In this case, it's the sound of digestion, or of trying to pluck up one's courage. For the term refers to gulps, be they of food or of air.

Onomatopoeia (occasionally spelled onomateopoeia or onomatopia, from Greek ????????????) is a word or a grouping of words that imitates the sound it is describing, suggesting its source object, such as "click," "bunk", "clang," "buzz," "bang," or animal noises such as "oink", "slurp", or "meow". The word is a synthesis of the Greek words ????? (onoma, = "name") and ????? (poie?, = "I make" or "I do") thus it essentially means "name creation", although it makes more sense combining "name" and "I do", meaning it is named (and spelled) as it sounds (e.g. quack, bang, etc.).
I hope that I don't make any sounds that resemble "glups". I thought that was where the word "gulp" came from (because it sounds like the noise made when swallowing.)
