When a girl is riding your face to the point you can't breathe and you feel like shes going to smother you.
So I was going 69 with this big girl and started freaking out when she laid down all the way and was twater boarding me!

Get the twater boarding mug.
When eating out a female her vagina covers both your mouth and nose and starts to suffocate you.
Jane likes to use twater-boarding a lot to gain information to thwart terrorist attacks.
