When you Shotgun a beer and use that beer as a waterfall bong at the same time, after shotgunning the beer you take the hit that is left over from the waterfall. and you have successfully completed the reddington
to successfully complete the reddington you need a Waterbottle full of beer with a hole at the bottom for your mouth, slide on top to pull after and something to smoke (legal of course)

Get the the reddington mug.
A unit of measurement, which measures how far an act gets you to getting laid.

1 Reddington means the action has directly lead to sex.
A few reddingtons can mean you are close (i.e. being only a few away), but negative Reddingtons means it has actually hurt your chances of having sex.
"So I thought helping this girl study for her midterms would just be a nice thing to do, apparently it was Reddington worthy."
"Really?"
"Yep, she fucked me"

"Hitting on this girl who already has a boyfriend was an awful idea."
"Go figure right? You're definitely in the negative Reddingtons now, and with all her friends she told too."
