A giant, pink, will-eat-anything worm from Alaska. As seen on the episode of Spongebob Squarepants when a fish-guy's butt got eaten. Along with Sandy's tail.

The act of taking a Popsicle, and using it as a dildo in your partners anus. Once the Popsicle has melted in the anus, you proceed to have anal intercourse until you spunk in the anal cavity. Once the spunkage has stopped you proceed to suck the sweet and salty mixture out of your partners anus.

An Alaskan Bullworm is a penile position where the erect shaft of the penis is held up against the stomach of the subject and the testicles are held by the free hand over the base of the shaft, with one testicle on either side of the shaft. the effect is a scene similar to the one in spongebob where the position's namesake, The Alaskan Bullworm, is charging out of it's tunnel. The worm is simulated by the penis and the tunnel simulated by the scrotum and testicles.

When one male ignites his falice with a blowtorch until blackened. Waits a few days for it to get encrusted with bacteria and puss, turning it white. Then running around in the nude with an erection screaming "It's the Alaskan Bullworm!" while attempting to give pedestrians the business.
Last weekend I blacked out and apparently Alaskan Bullworm'ed this funeral procession.
