A classic tactic employed by ugly girls who have a hard time getting any, the sneaky beaver is when said girl slips some roofies into your drink and takes you back to her place. As you gradually come to a few hours later, you wonder what your penis is doing in this stranger's vagina. Then it hits you, "shit, it's the sneaky beaver."
