WARNING: PLAYING IN THE FASHION MENTIONED LATER IN THIS POST MAY BE ADDICTING, AND COULD LEAVE YOU AT YOUR COMPUTER FOR HOURS.
Now that that's out of the way, let me explain. If you have a favorite light jacket or hoodie, PUT IT ON. THAT'S STEP 1. We want to make sure you're nice and cozy.
Next, you have to put on your favorite OVER EAR headphones. Earbuds are really nice, but this technique requires over ears 3:
Put on your hood, and then put the headphones on OVER the hood, so it looks really weird.
Play your favorite music via itunes, winamp, etc... on a low volume setting like 20-30, and then just play league of legends. The longer you're playing, the cozier you'll feel.
It's even better this time of year because it's kind of cold but not enough to use a heater.
You should look something like the picture at the end.
LET ME KNOW WHAT YOU THINK WHEN YOU TRY THIS, BECAUSE I AM ADDICTED TO THIS NOW.
I finally understand why people wear hoods inside.
Edit: Due to the downvotes I've added an optional secondary picture where you don't have to look at another human's face; just a poorly drawn human figure. I'm sure that version is much better and easier to understand.
