Phailm is commonly mispelled amongst the general population, and it should be noted it has a silent m at the end. It is part of the leet language, or 1337 language, it originated from the deepest darkest depths of the internet. Because it's part of the 1337 vocabulary, it is a pointless mispelling and has stupid characters inserted, like the term pwned. Phailm is used to describe the idiocy of someone or the failure of a certain task.
Person 1: I just bought a new Dell computer!
Person 2: Phailm!
