i

A prefix that originates from describing someone as inappropriate, e.g. "Inappropriate Dave", because they seem to have no social skills or generally don't seem to be able to say or do anything right. Can be added onto almost any word to denote that it is annoying, awkward, not very good, or just wrong. Never meant in a malicious way, however. The shortening to just "i" and the fact that it is always in the lower case with the second letter of the word in upper case takes its inspiration from various Apple products, such as the iPod or iMac.
