A species of Macaw known for its tendency to alight on one's erect penis. It is not clearly understood why these birds choose to land on penises.

Should a penisbird perch on your pecker, do not panic. The bird will most likely groom himself for a while and leave. Do not harm the penisbird, as they are an endangered species and must be protected.
There is naught more beautiful than a flock of penisbirds in flight, so long as you have your pants up.

The name for an origami bird with a paper 'tail' that protrudes in the wrong direction making it more akin to a huge penis.

Perhaps an attempt at a joke by the sex deprived creators of the origami instructions.
