A noun. An arsewank is something that is completely and utterly shit, but not to be used in an argument as the other person will most likely just laugh shitless. It is more as a jokey insult. It is best to be used in alliteration such as:
Autistic Arsewank
Acting Arsewank
Agrippy Arsewank
you fucking arsewank
BAHAHAHAHAHA
