a thong worn by a girl or young woman the top of which is visible because her pants have come down due to sitting or bending over Due to the accessibility of the thong, men might be tempted to give it a pull.
Attempting a task that has been dumped on you by somebody who expects a miracle. Like your dumbass boss who left two hours ago and wants you to get something done in an hour that would have taken him all day to finish. A takeoff on "Hey Rocky, watch me pull a rabbit out of my hat!" from the Rocky and Bullwinkle cartoons.
'The boss expects me to get all these reports done for the corporate office by tomorrow morning, I don't think I'm gonna make it.' 'Well, you know how Steve is about that. He bails and now you have to say "Hey Rocky, watch me pull a rabbit out of my ass!" just like the other days of the week where he is working 27/4'
--OR--
Rick left early again, now I gotta pull a rabbit out of my ass to get this computer fixed.
