A bag of marijuana that you offer to sell to "customers" along with a variety of other dank strains, just so they will be tempted toward the curious name. In reality, crazy blue sillies is a bag of roaches that you sell the poor sucker for sixty dollars an eighth.
Yo man, I've got three different types that I'll sell you for sixty dollars an eighth: Sour Deisel, White Widow, and, my favorite, Crazy Blue Sillys." "Wow man, I've never heard of Crazy Blue Sillys, but it sounds really really dank." "Alright dude, that will be sixty bucks." "Here you go man." "Thanks here's your bag" (leaves) "Crap!! that guy gave me a bag of roaches. shoot.
