(n.) The end of ones life, as described by those who claim to have had near death experiences.
Then it comes to be that the soothing light at the end of your tunnel

Was just a freight train comin' your way, hey... yeah...

The pin of light you can see on a girl between the thighs and right at the vag. The light you hope to be able to see, because you know a number of things from the existence of that light:

1. She's at the very least in shape where it matters most
2. The area is properly ventilated
3. It's going to be tight

This term predates the misinformed "thigh gap" as it is preferred to have the thighs touch towards the top but have that pin of light exist. It has become lost knowledge that must be re-released to the masses.
You see that girl in the stretchy sweatpants walking away from us? Look at the top of her legs. You see that light at the end of the tunnel?


THAT'S what you want. You make sure the girl you're going for has that, and you'll always be in a good spot. Guaranteed.
