Retarded flamingo
The constant cringing of the leg after one's foot is no longer asleep, and they try to walk on it. It looks similar to how flamingos will hold one leg up, hence the name.
"I don't want to get up, because my foot's asleep"
"Trying to avoid the retarded flamingo, eh?"

Retarded Flying Flamingo
When a girl is having a foursome with 3 guys. 2 guys standing to her sides and one in front. the 2 guys on her sides get handjobs and the guy in front gets blown. The part that makes this different than the flying flamingo is that the girl does everything not simultaneously. This makes the girl look like a retarded flying flamingo.
I walked in on my sister, she was doing the retarded flying flamingo.
