The Bird
The Bird is a complicated sexual maneuver.  Successful completion requires five (5) people, one of whom is The Bird.

The Bird takes one dick from the back, one dick in the mouth, one dick in their left hand (while the person stands on The Bird’s left), and one dick in their right hand (while the person stands on The Bird’s right).

Bent over with all four (4) penises in position, The Bird jerks their arms back-and-forth while rocking their body back-and-forth.  They look like they are trying to fly away, hence, The Bird.
Dude, I just walked in on the sickest shit I have ever seen!

I caught Nathan, Matt, Jon, Mitch, and Dave doing The Bird!
