Nika is so tough she Flosses her teeth with nails and rinses with roundup. Nika is so tough she goes bungee jumping without a cord...She plays Russian Roulette with 6 bullets...how tough is Nika...what have you got?
Nika's so tough she files her nails with a power sander.
She shaves her legs with a broken bottle.
So tough that she will never/ever have a street named after her. Everybody would be afraid to cross it.
