When youre getting a hummer and right when youre about to blow........smack her on the back of the head to make your load come out her nose.

When a woman is going down on a man, right before he ejaculates he pushes down on the back of her head (or punches her in the back of the head) causing he to choke and cough thus shooting the semen out her nose. Like a dragon shooting flames or ice of it's nose.
