Are oh are why

Smile the best is yet to come (Scottish slang)

1: I’m having such a bad day!

2: Don’t worry, are oh are why!
1: You’re right I guess

you are bee a and d i see tee oh and a are why

When you're extremely bored and start typing "u r b a n d i c t o n a r y" but different.

"you are bee a and d i see tee oh and a are why" is just:
you = u

are = r

bee = b

a = a
and = n
d = d
i = i
see = c
tee = t
oh = o
and = n
a = a
are = r
why = y

Oh fucking why

When you are either pissed off, hopeless, in trouble, or suffering, or maybe all at once. Literally means "why is this happening?", but in a less nice way.

Guy1: homeless
Guy2: takes the guy's stuff and hits him with a bat
Guy 1(crying and pissed): Oh fucking why?!
