Is "sike" a word that you use? In what meaning if so?
My mum's family call the stream at bottom of the hill in the village they grew up in the "sike" but I've never heard anyone not local to them use it. I've always assumed it was almost a dialect term.
I've also recently seen this as a (deliberate?) misspelling of "psyche", which is a (teenage?) (American?) slang term used to express that the dialogue just before it was a practical joke of some kind, an attempt to "psyche out" the person you were talking to. I think the misspelling is an attempt to stand out or identify with youth culture in some way. Or, of course, the people using it could just be lazy
