Pinochle is a confused part of A.S.C.O, due to it's recently introduced status, little is known about what relevance it has to with A.S.C.O. It may be the "signature", chosen to disguise the SECRET even more. It may have to do with Blackle A.S.C.O, the account on Wikianswers for A.S.C.O.
Kaleb Oaten did once speak of Pinochle, however the file containing the information is thought to be destroyed or missing. This piece of information has been "unearthed" since a possible clue was found at the end of Blackle A.S.C.O's profile page. See Blackle A.S.C.O
Linked from childrens websites, and is considered to be even more disgusting than goatse, tubgirl or harlequin foetus.
There are actually many pictures of "asco"s. Google image search brings forth a rotten.com picture of two severed heads with dismembered penises in thier mouths, and think-evolution formerly hosted pictures of very old naked people, and a masturbating shemale.
B: "I hope you die, you sick fuck."
A: "Hey, what was the link to ASCO?"
A: "Thx" *prints out to masturbate to while in the shower.*
