Exactly the same as the bassalisk from Harry Potter, except that it is made up of Ass'. It is entirely more sneaky and cunnig than an actuall bassalisk and has sexual relations with dumbledore and Harry. Niether of which know about the others relationshio with the assalisk.

This can also be sed as a common phrase to describe someone as a cheater, or a devlishly sneaky and evil being.
Did you hear Lee was cheating on his girl Atlanta? Yea he took all her money and her house.

That dude is an assalisk.
