having a pencil dick is similar to drawing a picture that came about from you falling through a skylight and landing on a table which has a penicil standing up and landing on it and the pencil goes up your japs eye. When the pencil protrudes through your purple headed warrior you know that your pencil dick is HB quality.
"Oh, that's a bit of a DICK PENCIL"
"That guy is a dick pencil"
"If I was writing your name, I'd use my dick pencil"
"Can you write your number on my tit with your dick pencil?"
"Anybody got a spare dick pencil?"
"All schools should supply dick pencil quality HB"
