What doesreply guymean?

It can also refer to a person who frequently and zealously responds to posts from famous people on Twitter.
Where does reply guy come from?

Reply guys didn’t always have such a bad rap.
Many brands, such as Wendy’s and Netflix, personify their brands in their social media accounts. Oneearly adopter was the restaurant chain Applebee’s in 2012. Their Facebook social media manager would notably reply to comments on the site, earning the nickname Applebee’s Reply Guy thanks to their humorous and endearing replies.
But as early as 2015, reply guy became associated with someone who replies immediately and obnoxiously to posts on Twitter, especially in reply to famous people. As if they have nothing better to do but wait around to weigh in on a topic with their two cents.

By 2018, the gendered nature of reply guys was on full display, particularly their tendency to mansplain ǰpresumptuously flirt. In September of that year, scientists @shrewshrew and @sbarolo offered a hilarioustaxonomy of nine different kinds of reply guys“who repeat the same unhelpful comments.”

In November 2018, author Emlyn Crenshaw wrote a parodicalpiece fǰѳɱԱ’titled“Reply Guy Constitution,” an excerpt of which humorously summarizes the reply guy mentality:
For the good of the Internet and the preservation of Male Excellence, We shall weigh in on women’s thoughts at every possible opportunity. Never shall We leave a comedian’s jokes un-improved or a female’s observations un-corrected. Eternally shall We pipe in.
