Pseudonym of 1LT Jaclyn Gill of the 94th BSB, 4th Brigade, 10th Mountain Division, Fort Polk, Louisiana. So named because she made some (bad) amateur porn in college and in one video, (after a BAD blowjob), swallows a guy's load through a blue funnel inserted into her mouth, then wipes it out with her hands and licks it from her fingers. She is also a total bitch who is the personification of incompetence, pure evil, and has a busted-looking rotten snatch.
Person 1: "Did you see the video where Jackie drinks the jizz through the blue funnel?"

Person 2: "Yeah, it made me puke so hard, my dog jumped out the window. Blue Funnel's one disgusting bitch."

Person 1: "I'd hit it."

Person 2: "Yeah, with a stick maybe."

Sheets and funnel is a DMV slang term. Sheets refer to Bambu rolling papers and funnel refers to a lose leaf tobacco. This "funnel" is mixed with cannabis and rolled in a "sheet". Sheets and funnel is preferred by many people in the DMV over Backwoods and other blunts given multiple factors. These factors include: more economical, less chemical additives, better & slower burning.
