A similar glyph (called "double-dot wide O") has also been humorously suggested as a phonetic symbol for the "nasal-ingressive velar trill" (not to be confused with velaric ingressives or click consonants, a set of sounds which don't include trills), a paralinguistic impression of a pig's snort, due to the resemblance to a pig snout. However, the glyph used thereupon is slightly different and was intentionally created, rather than directly stemming from the binocular O.[1]
