Someone who is so miserable they bring you down and sap your happiness.

Serjstache

Fashioned out from the lead vocalist of S.O.A.D. or 'System Of A Down'. Best band ever, imo.

Used to describe someone with facial hair that exceeds all known descriptions. Usually put on someone with an UNGODLY amount of facial hair, either that or he has some crazy, wicked, yet awesome style to put it in.

Serj Tankian, be the owner of the serjstache, naturally.

Duuude. I saw Malik in Tajihjkistan. He's got a frikkin' Serjstache.
....
He's not gunna get to the airport, is he.
Naw~ I dun' think he is. D:

Sero Hanta

Sero is an ethereal being that can shoot tape from his elbows. Hes perfect in every way shape and form. At this point Midoriya is just a backround character, because damn, Sero really be the best character.

serodronin

1: the state of consciousness present after one has exhausted their supply of serotonin, effectively rendering them to human drone status

2: the afterglow from MDMA or ecstasy which causes one to aimlessly wander as if a brainless drone

"Dude Tom has been super out of it since the rave last night"

"Yeah, he's serodronin yo"
