Lady-stiffy
When a girl's crotch area is so excited it's like it's doing a backflip and shouting 'I'M READY!'
I got a lady-stiffy when my crush texted me 'I miss you.'
During lunch, my lady-stiffy was so strong my sandwich fell on the floor.
I got a lady-stiffy while walking by the vending machine and my snack flew out of my hand.
