I Perversions

Recently I've found a new pervy but it's not what you're thinking about. It seems to be kinda popular today and even here on SW I've found some recent post about it.
That's the only hint (who cares? Really)

SHHHHHTHTTTTTT !!! That's a secret!!!

So why are u telling this SHARKO? Cuz I wanted to ask things about Brexit but I don't wanna think about this complicated kind of stuff, it's half past midnight here, etc.
