@RegDwigнt Interesting take! It is close to Robusto's comment, that I upvoted: "It's a false oxymoron...". Also interesting that there is a german word Body Bag that is not bodybag... I can understand a fair bit of German (based solely on being dutch) and this is quite a funny false cognate.
You are arguing that it a false oxymoron, which I can sympathize with. In fact, I had read BenHocking's comment and immediately felt that pedantic tingling feeling that said "this guy doesn't even know what an oxymoron is!". But, as I tend to, I researched that 'fact' first, and found that there is a huge number of references including 'pretty ugly' as an oxymoron.
This struck me as being at odds with 'certainly probably' not being an oxymoron, an answer that got +50 on here. I didn't find an answer and posted it here to find out.
@RegDwigнt However, I am now no longer so sure it is, in fact, a false oxymoron at all. You see, the false cognates you put forth as evidence are clearly breaking some 'rule', misattributing meaning to a lemma, but any definition of oxymoron I found does not require the meaning of the lemma to actually be the contradicting.
If you have an open mind for a second, it is actually insultingly trivial to see how misguided one can be by following 'logic' here, when what makes an oxymoron is the human experience of contradiction - not the logical contradiction itself. Deafening silence in fact does not mean that the silence makes anyone deaf, it is a stylistic element to make a reader think, and give greater vehemence to the 'silence'.
This is reached through Positive priming, as psychologists call it, a contradictory thought. That same stylistic goal is reached with 'pretty ugly', which - I believe - is why so many people experience it as an oxymoron.
--- it all leaves me very sad that a clearly wrong answer is being upvoted. My question is considered 'off topic' for no reason at all and is still closed. A simple link here would've been more helpful than the rubbish people agree with without thinking:
en.wikipedia.org/wiki/Oxymoron#Apparent_oxymora
(I didn't mean positive priming === contradictory thought, just that the things that are primed by 'pretty' can be contradictory to 'ugly', and that this contradiction could suffice for any definition I've come across)
