Get the Birdo mug.
The pink Yoshi-like creaTure in Mario games. Can spit eggs and is apparently having an affair with Yoshi.
Both Birdo and Yoshi can produce their own eggs, so they are hemaphrodites.

Get the Birdo mug.
One of the more disturbing characthers from the world of nintendo Mario. S/he is a possibly female yoshi sporting a pink bow-tie, too much mascara, and a maybe fake beauty mark. Also, eggs come out his/her.... mouth?
Birdo was in Super Mario Advance, but dont rush out and get it.

Birdo is a transfemme character in the super mario series. She is often mistaken for male though she is canonically female (mtf)
Brian: "Birdo is not trans, he is a man!"
Alice: "Either Birdo is trans or Yoshi is gay"

Example 2: “That birdo got into the trash again!!”
