ARF

Acronym for Adolescent Retarded Fool. Someone who is an ARF is someone who is immature, insecure, stupid, slow-witted, overconfident, and completely convinced of their own superiority, without having any merit whatsoever.

Friend 1: "Did you hear what that guy was saying to his girlfriend? What an ARF!"

Arf's Dong

Originally thought to have been a conjoined twin at birth, Arf's Dong is so large that it is typically used to describe how big or small something is in relation to his unit. Experts state that whenever an erection is formed his heartrate increases roughly ~300% in order to compensate for the blood loss in his brain as well as maintain his throbbing member.

Wow! Did you see that giant pile of elephant shit?
YEAH! It was almost as big as Arf's Dong!

I'm not so sure it would fit.. Sure it will. If Arf's Dong could fit, anything can!

`arf-quid

`arf-quid means half-quid. It is not untranslatable "old-speak", it is simply eye dialect. A "half-quid" is half a quid. A quid is slang for a pound sterling, analogous to the use of "buck" to refer to a US dollar.

"Here's you a-comin' and arskin' of me questions about my business, and I that grumpy-like that only for your bloomin' `arf-quid I'd 'a' seen you blowed fust 'fore I'd answer."

"An' when you said you'd report me for usin' of obscene language that was 'ittin' me over the 'ead; but the `arf-quid made that all right."
