At a guess, it's pizda (пизда) with '*' replacing 'z'. Think pus*y, but not referencing a feline. No idea why the asterisk - unless it was a translation of пи*да.

I'm not a Russian speaker, BTW...

I won't get into how I find the misogyny in using female anatomy as a way of saying 'weak' offensive (oops, looks like I just did).
