Excellent. Now that, as I'd hoped, it is confirmed that the Chinglish we are looking for here does certainly include the completely strange and utterly wtf random appearance of English (however properly spelled and grammatically correct) that could only find it's way onto a t-shirt like garment through the filtration unit we all know and love as the big silly, how about another?
Obviously, this fits neatly into both aforementioned categories. Now then. Does this little collocation make you think of anything other than FLATULENCE? I don't think I'm being at all primary-school-recess in posing the question either. I suppose if I dig deeper, I might come up with pamphlets warning against the dangers of glue-sniffing or similar warnings on various product labels ... but... but it's so VERY proclamatory here, isn't it?
... an odd choice to say the least.
It makes me sad because I think what happened here is the young lady saw the word 'powerful', recognized it, and said 'YAH, I identify with that!', and she never, not for a shred of a nano-instant, thought to hit up ye olde iphone dictionary for a bead on the noun...
.SIGH.
