Proofmeister 

Someone who continuously reads scientific and mathematical articles on Wikipedia in an effort to learn the derivations or proofs behind equations and concepts from high school science and math courses. Other symptoms include obnoxiously disrupting the class to ask teachers to show proofs or derivations (e.g. the derivation of Newton's Second Law) but rarely getting a response. The student may even email Michio Kaku to resolve a physics debate between two students in the class.

Student: Please show me the proof for the Fundamental Theorem of Calculus, Part II.

Teacher: No, you proofmeister!

-----

Student: How do you derive K=1/2mv^2?

Teacher performs proof.

Student: So now can you derive U = 1/2kx^2?

Teacher: No.

poonmeister 

a growing phenomenom, poonmeisters are sprouting up all over the joint. what is a poonmeister? a true meister of poon. this guy lives poon and loves poon: his weekend involves going to parties, getting with the best poon there, and then fucking the hostess. he will have no problem with two timing or cheating on girlfriends.

targets for a poonmeister to achieve:
14 years old - get with 20 girls
15 years old - get with 30 girls
16 years old - get with 40 girls
and so on..

all girls must be above 6.5, no cheating.
you can only be a true poonmeister if you have achieved these targets: only then can you truelly be called a poonmeister, the meister of all poon.

poopmaster69 

An epic username for every pro Fortnite player.
Also means the act of poop in a man's butthole and asking him to poop into your mouth, so you'd be eating your own poop.

"Dude, I'm so mad that Poopmaster69 killed me!"
"Bro, some homeless guy asked to do the Poopmaster69 with me."
