"'Tis some visitor," I muttered, "tapping at my chamber door--
Only this and nothing more."

from Edgar Allan Poe – The Raven on Rap Genius

Meaning

Señor Poe was in the midst of a dreary hypnagogic jerk. Nontraditional lore indicates that Sir Poe was coming off of a keg stand of tea— the royals addressed Poe as “Fancy-toe Poe”, due to his remarkable ability to do elegant tea keg stands while flaunting his nimble pinky toe in the night sky.
