The Human CentiPad is a fictional creation in the season premier of season 15 of South Park. It is a play on the creation of an evil German plastic surgeon and the movie The Human Centipede, in which three people are joined together A2M in order to make a creature with one gastral tract.
The Human CentiPad is the same as mentioned above, but has an iPhone attached to the fact and iPad attached to the rectum. Kyle Broflovski forms the infamous "middle piece." It has 3G capabilities and does not know how to read. It prefers cuttlefish and burritos as its main source of food.
Since Eric Cartman was f*cked by his mom in a Best Buy, Steve Jobs decided to give Eric the first ever Human CentiPad.
