What Does OCO Mean?

OCO means "Oh, Come On." The abbreviation OCO is used to express disbelief in what someone has said or done, or when the sender does not want to accept what they have been told. The use of OCO usually implies that the sender does not believe that the other person is being serious.

The phrase "Oh, Come on" was probably most famously used by Jim Carrey, in the 1997 film "Liar Liar."

An Academic Look at OCO

OCO is used as a standalone declarative sentence (i.e., a statement). It is not used as another part of speech within a wider sentence.

OCO is an initialism abbreviation. Technically, this means it is pronounced using its individual letters (i.e., Oh Cee Oh). However, it is not usually spoken using its letters. The abbreviation OCO is for efficiency in writing, rather than for efficiency in speech. Initialisms are different to acronyms, which are spoken like words.

What Did We Say before Texting and Social Media?

Before the digital era, we might have just said "Oh, Come On" or something like "You can't be serious," instead of using OCO.
