I don't know what you are doing, but I can tell you are doing it wrong!

Why should I tell you?

It means they don't know, or are a stupid troll.

"Ok, if you're a genius, then what's the square root of 6456?"
"Why should I tell you?"

The last thing you hear before being stabbed in the chest by a 10 cm long knife in north London. Could also be in Birmingham or Glasgow. Whatever you do if you hear this sentence run away.

Bruh, I'll tell you what mate

I'll tell you when you're younger

1. An incredibly annoying way of stating that you just don't want to tell them something; might be for personal reasons. (Knowing that you cannot get younger; it therefore means one will never tell them what you are referring to.)

Caitlynn: Why won't you look at my face when we make love!?

Me: *turns away and thinks to self "ah crap, here we go again... c'mon, think of something!* ...I'll tell you when you're younger...
