A ruiner is a way of fingering a girl using 3 fingers, two in the vagina and one in the anus.

The ruiner is made using your index finger, middle finger and your little finger with your ring finger bent inwards.

The Ruiner - Two in the goo, one in the poo.
Two in the pink, one in the stink.
I used the ruiner last night, she screamed so loud she woke the dead.
