Sin-in-law

The relationship a boyfriend has to his live-in-girlfriend's parents.

Girlfriend: Mom, Andrew and I are moving in together

Mom: Oh, you're going to live together before marriage? Great, how I've always wanted a SIN-IN-LAW.

Girlfriend: But we love each other!

Mom: That's great, your love can help keep you warm right alongside the BURNING FIRES OF ETERNAL DAMNATION

Sin π

Used by people as a clever way to say "Senpai" because.... I actually don't know why.... they just do it because it makes them sound clever as it's a mathematical phrase. If you see someone mention this then they most likely stole it from Reddit so if anyone somehow get's extremely popular by saying this at school or other places then you know where they got that from.

Jimelf: "Notice Me, Sin π! HAHAHAH I'M SO FUCKING FUNNY HAHAHA"
Agent: "FBI OPEN UP!"
Jimelf: "Oooopsydaisy I think it's the feds I must hide!"
Agent: "Open this fucking door you retarded twat" *Breaks down door*
Jimelf: "STAND BACK I AM A CLASS 6 WEEB!"
Agent: "FUCK! CALLING FOR HELLSTORM ON COORDINATES 41°24'12.2"N 2°10'26.5"E"
Jimelf: "Ima kuso inbu o bakku sutando" *Shoots some fireball or some shit*
Agent: "AHHHHHHHHHHHHHHHHHH" *Dies*
*Hellstorm missile 40 metres from the ground*
Random AC-130 missile: *hits Hellstorm missile and creates massive boom*
Hellstorm missile: *Bounces of the other missile and hits the sun and the sun explodes and kills everyone and the earth turns flat*
