1. A sick dick occurs when a man's fully erect penis is so mighty that it causes "bitches to be Trippin" or another man/woman to say "aaaahhhhh" or "ooohhhhh" in a drawn out manner.

2. When a man's pen-is mightier than a sword.

(in both definitions the word sick is from the sk8r term meaning awesome or "rad")
Man: Behold my PEN-IS!

Woman: aaahhhh.. that is a sick dick!
