Geriatric teacher 

A miserable old sod, usually with a beard, who corrects anybody and everybody at every opportune moment. Particularly anal about poor grammar. A geriatric teacher tries to remain relevant by wearing cartoon socks.

Instagram Teacher

An older sibling who has social media and teaches you how to use it properly, or insists on you getting it so they can do so.

"Yo, my instagram teacher just taught me how to use a filter!"

"Man, I wish my older brother was an instagram teacher"

Math teacher 

Someone who is guaranteed to make your life a living hell, however this part of hell is known as school, in a math class your sanity is drained and you want to die.

Me: “Hello Mr. *insert Math teachers name here* we are going to be late if you don’t let us out of class.
Teacher; don’t check your watch. You’re not leaving.

Me; NOOOOOO

Science teacher 

A science teacher is someone who teaches science to a group of people usually students. They are usually stubborn and impatient and tend to make there students do useless things called "labs". They are super important in our education.

My science teacher, Miss Durdia is a stubborn bitch who teaches us nothing but how to survive her annoying ass.
