What meaning is ”opps” ?

上面兩位講到似曾曾,
雖然答案是對的, 但其實提問者是寫錯字,
應該是 Oops
= 表示驚訝、狼狽、謝罪等的叫聲)哎喲!
(from yahoo! dict)

opps - is a reflex when you heard something unexpected or surprised.
例:
John: I felt badly in a basketball game last night.
Jack: Opps! was it serious?
opp: also an abbreviation of OPPOSITE.

Sorry
串錯字: John: I felt badly in a basketball game last night.
應該是: John: I fell badly in a basketball game last night.

It means that something you have done is wrong,

it just a response.
