"Rob my cat like a fenji" if a female says it to you, they want to have sex with you. Its a flirty thing to say.
Cat stands for the vagina of the female.
Fenji isn't a real word. Its just a thing you say sometimes.
With rob my cat like a fenji the girl kinda means "Fuck my vagina hard and soft" but thats not the actual meaning
