Search the web for the phrase "I cosay". I run across this phrase being used from time to time by individuals in tech forums, but for the life of me, I cannot figure out what it means or how it makes sense in the context of the conversations where it is used.
Am I just way behind the times? New slang?
Without context, I'll have to say a cosay is the counter-say in the same vein that cosine is a counter to sine.
As far as I can tell from the contexts Google pulls up, it is a very poorly machine-translated form of "codigo". "digo" or some variant is "I say", so it forms it as "I cosay" when it really shouldn't be translated at all. Roughly translated it should probably be "code" or "encoding".
from the context of usage it looks like slang for agreement - you say X and I cosay X - possibly invented by non-native english speakers - but that does not cover all of the contexts of usage...
In french from Quebec (not France) it means : "I do not understand what you are talking about, can you repeat?" but it's a very low level of language... nothing official and shouldn't be used ... often kid use that type of expression...
