Ricky growing up was the cool kid in the park (at least according to Corey and Trevor), however in his adult years all he's done is go to jail, grow dope, live in a car, and get drunk and shoot guns. He frequently uses incorrect pronunciations of words (Cannepillar, Nay-sa for NASA, etc.) and goes on rants which leave everyone wondering what the fuck he just said. These speech habits are referred to as "Rickyisms".
Despite seeming somewhat unintelligent on the outside, Ricky has a great deal of experience and knowledge in "practical" fields, such as growing dope and stealing car parts, and of course, playing hockey. He also has a good heart and seems to want to satisfy his love interest Lucy, who is the mother of his daughter, Trinity, who Ricky loves unconditionally.
He is also able to extract cigarettes from Trevor any time he wishes, simply by delivering the catchphrase "Let's go, 2 smokes" or "Smokes, let's go"
(cuts to Ricky laying face down on the street)
Put in most basic terms, the perfect person.
Girl 2: "Oh that's Ricky, you know krb."
"Yeahh, he's so ricky!"
