When you shotgun a blunt or joint into one of those frozen frosty mugs and fill it to the top with smoke. The smoke will drop in temperature and look like liquid sitting inside the mug. Tilt the mug up and inhale (like you're drinking it) and you'll get a rush of cold goodness straight to your head. Definitely a kick ass way to smoke, and HIGHLY recommended!
