The “Grammar Nazi” meme is for someone who regularly corrects grammar mistakes both online and offline. Usually, this meme has a negative connotation as it ruins a good mood.
The original version of this meme was that of a blonde teenage boy with plaid sweater and braces captioned with various embarrassing scenarious. Through time, the meme took on different versions and this is one of them.
The Hello, This is Dog meme started out way back in 2011 as posted by VivaDixies, a Tumblr blogger. The image or GIF associated with this meme features a black anthropomorphized Labrador looking as if it’s answering the phone.
