An interstate in Maryland that can get backed up at any time even though it is 6 lanes on each side at one point.
It's a miracle, no traffic!

270
A covert way to tell a person to screw them self, or a way to insinuate that a man is literally screwing them self. 270 is the angle of the penis necessary to perform such maneuver, hence the brief and scientifically perfect synonym for an otherwise vulgar gesture. It is also a great way to respond to a person who is bragging about them self.
1. Oh really, did you do that with our without your 270 in action?

2. Really buddy, just go 270 in your room and get it over with. We already know.

3. Hey pal, go 270 yourself. Dry.
