Whether you have a toddler that you need to park in front of a screen before you turn crazy of you just want to go insane yourself, here's a good option:
At heart, contrary to what your brain may be telling you, Giga Pudding/Puddi Puddi is not a Japanese brand of pudding; it is, in fact, custard.
It is also the street name for a new drug that is making the rounds in American elementary schools, mixing pudding mix with such known downers as Nyquil, Advil and Vicodin, as well as anti-freeze and Drano. Cool enough to give you a soft buzz with a sweet taste, but in the wrong dosage, very deadly and/or able to cause permanent damage.
S it's no surprise places like 4Chan went nuts with in this winter and it became a meme.
