Omni rage

a satirical rant as 'omni Greggs rage'

You may have watched The Thick of It, in which Malcolm Tucker, played by Peter Capaldi, characterises someone as an 'omnishambles'. It caught on because it is an excellent word. So I don't know, but I think that this use of omni in this facebook post might be an example of it going wild (the post it refers to isn't for real, but it is a convincing pastiche of a certain type of person).

Omni is a prefix most of the time. It means 'every', like in omnivorous. Prefixes can cut loose from their roots if they're typically used in one specific word, or if the free version has just one meaning. So, for instance, cis means cisgender because we don't really use cis for much else (though we could - cisalpine is a word, though not a common one, meaning 'on this side of the Alps', where 'this side' means with respect to Rome - it's a Latin thing). So cis has specialised into this one meaning. Other gender- or sexuality-related prefixes have similarly gained independence, so you can describe yourself as bi, meaning bisexual, even though we have the bi- prefix in loads of words (bicycle, biped, biennial). It's just with that one meaning that it can be used solo.

I checked Urban Dictionary for omni and quite frankly didn't understand most of the definitions, so I'm not totally sure what's going on here. I didn't find anything that suggested it's used alone in the omnishambles sense but that really does look like what it might be. Omni rage as a term for that pure, hysterical rage as displayed by Malcolm Tucker in full flow?

(If you're not in the UK you'll have no idea what anything in the facebook post is about but don't worry about it; it's just the latest nonsense. Basically, professional moron Piers Morgan threw a hissy fit about 'snowflakes' when Greggs started doing vegan sausage rolls and people were quick to point out the irony of his rage about something so harmless.)
