Sab Varun Ki Wajah Sei

This expression is used to blame everything on Varun.
It is culmination of 5 words of Hindi
which literally translates to 'Everything is because of Varun'

The expression is used as a joke to forward the blame to a person named Varun(who most of the times wasn't even present at the scene)

Teacher: "Who was the one to break the window"
Everyone: "Sab Varun Ki Wajah Sei"

Kimi no sei is the opening song of the anime Seishun Buta Yarō. A weeb tends to sing with the opening, especially when it starts.

Person 2: "Dude, whats wrong with you?"

Sei 

To be incredibly epic at basically everything. Seems to be from a different dimension, though this is up for debate. Will not admit to having ninja skills even though said skills are witnessed regularly. Prone to anime-type reactions (aka loud and obvious), usually ending in some form of destruction.

Person 1: WTF happened in here!? All the desks and chairs are destroyed!!
Person 2: Someone pissed off (insert random name here).
Person: What an idiot, everyone knows (insert random name again) is a Sei.
