Top Definition
A sex act which consists of the severing of the male penis (usually with shears). The severed penis resembles an "Alaskan Bull Worm," a fictional beast from the SpongeBob SquarePants mythos.
Betwixt the howls and throes of passion, Billy performed the Hot Alaskan Bull Worm - an act that he regretted shortly thereafter.
