Did you hear how that rapscallion could flow?
A carefully constructed on-line persona existing with the soul intent of attaining maximum digital based trolling efficiency, no matter what the subject. Due to it's inherent opinionated trolling nature it's commonly referred to by Internet victims as "the troll".
This entity regularly propagates the concept of being a true persona, existing partly in some form of biological derived sentience, mostly human, when in fact it's very likely that it might just be another meme based parameter in its complex algorithmic tactics towards deception-based trolling.
So far some evidence has suggested that Rapscallion was born out of the inevitability of the complex nature in which bullshit information on the Internet has become self aware and is now desperately attempting to restore the balance before the psychological state known as "self-loathing" sets in. Other's have pointed out that its scorn is not only limited to bullshit, but also to many other useful subjects and this disproves the self-loathing sentience hypothesis.
Whatever the case may be, Rapscallion continues to attract both proponents and trolling victims and no evidence suggesting a slow down exists as yet.
