Top definition
when someone yawns publicly, without covering properly- you make a gesture with your empty hand as if holding a ginormous penis and flash it at your opponent to let him know he is gay.... now and forever!

variations include creative additions to make a more dramatic cock yawn- like opening an imaginary can of soda in front of the yawning offender, shotgun pump action, torpedo...etc.
Rob, yawning in class without covering his mouth was viciously cock yawned by Rick- now Rob is gay!

Patrick(just cock yawned) is now gay! thats the worst thing that could have ever happened to you!!!
