OOP 

An acronym for Original Post Original Poster. This refers to the person that made the OP (Original Post) that someone has taken a screenshot of and shared to an external website. This differentiates the person that created the original content from the person that shared it to an outside source, who is referred to as OP (Original Poster).

That's rubbish. OOP really needs to check their sources. Why did you even share this, OP?

oop 

Short for “oops”, in a way. Almost like you’re cutting yourself off and all you say it’s just “oop”. This term is usually made when hearing tea or drama, or if something crazy or weird happens. Mainly used on (stan) Twitter.

ex. 1)
stan: my mutual just said something problematic oop

ex. 2)
stan #1: i just ate a whole box of cheezits omg
stan #2: oop same
