OH: 

Abbreviation for "Overheard," used to preface a quotation or piece of dialogue on social media and online forums. It signifies that the speaker has eavesdropped on or incidentally heard the quoted conversation or remark, rather than being a part of it themselves. This prefix is commonly used to share amusing, insightful, or peculiar statements picked up from others, emphasizing the speaker's role as an observer rather than the original source of the comment.
