Props to the translators who know it's "Psych" and not "Sike," which is not a word in the first place. The pedant in me is pleased.
What you mean is "sike" isn't the right word for that situation. Sike is an older word, but word it is.
“Sike” is not a modern English word. It may be a slang spelling of “psych,” which is a shortened form of the idiom, “psyched you out.” “Sike” is also a pre-modern spelling for words such as “sick” or “seek,” and a Scottish dialect word for “a small stream.”
But in this context “Sike” is not a recognized English word.
