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.
A strange, featherless bird shaped like a man's genitals, with a beak on the front of the penis' tip. Common prey of the wordgorillaroo.
Don't make me shove a penisbird up your ass.
