look up any word, like blumpkin:
The act of ejaculating on someone and then throwing feathers onto them. As a rule, only truly accomplished when the feathers are yellow, but white will suffice.
I was running out of things to do to her so I tried big birding. Everything was going well until I realized the feathers weren't yellow. I'll get her next time.

Falling asleep seated on the couch with your head down so that your chin is touching your chest, like Big Bird sleeps.
Kid: Mom ... you might want to go take big bird in here to bed.

Mother: Is your father big birding again?
