That would still be grammar as it refers to usage, not a misspelled word. I mean, I could, if I were so inclined, ridicule his grammar as well. It’s ironic that he’s being pedantic because, much like you have done, he didn’t separate the interjected name from the initial greeting (i.e., it should read as follows: “Hey, Jess” or “Hey, Genocide”). Also, Kat, if that is your real name, you should’ve placed a comma after grammar. Furthermore, the use of the past progressive “was referring” is incorrect; he was not referring multiple times in the past.
Secondly, I am not an idiot, but you clearly are. For evidence of this, see that you called me “Genocide.”
I love how everyone who criticizes anything on this site is bound to get reamed a new asshole and given an intense course in grammar… and yes, Herpfest, herpes is an absolutely HILARIOUS disease, we get it.
