The sexual act of performing fellatio and simultaneously jerking off two penii. This motion resembles that of a teradactyl in flight. Related to skiing, but arms are raised, and mouth is open.
I used to think that the teradactyl was extinct until Bruce, Dante, and I met up with that ho-bag Tina.

Rob did one helluva teradactyl last night...
