Idiot Pedant 

1. A person that invites himself to lecture you about anything and everything but in reality is a complete dumb-ass.

2. Much like an idiot savant, the idiot pedant really is an idiot.

After Eric decided to give us the three-hour lecture on golfing, that was completely wrong, he just cemented the fact that he’s an idiot pedant.

Calendar pedant 

The annoying ass people who don’t stop insisting that the new decade begins in 2021, and not 2020. These are the same people who complained in the late ‘90s that the new millennium doesn’t begin until 2001 (Even though 2000 was a bigger deal than 2001) and that the 2010s “isn’t” a proper decade, and that it began in 2011 and ends in 2020 (Or ended if you’re post reading this post 2020).

Usually a Sci-Fi fan, the type of people that loves Star Wars, Geeky, and most of the time, have no friends.

Joe: Sends his five friends invites to his new decade party that is held on December 31, 2019.
Toby replies to Joe: The decade doesn’t begin until 2021.

Joe disinvites Toby after realizing he’s a calendar pedant.
