It’s weird but is it really a FML situation?

Are any of your pets missing?

Maybe the experience of watching the movie together was "delicious" to one of your roommates, or friends.

Probably just a goofy metaphor for "very nice". I have been told my outfit was "delicious" before. The kids these days never stop calling cuties "a snack". I can't recall a night out ever being described this way but I can easily believe either I am just unaware of such or the note leaver is awkward, ditzy, or was intoxicated, and they clumsily misused an expression. Or it was intended to be clumsy- acting dorky ironically to be funny isn't rare.
Or if you insist it was literal... is it possible they ate a decorative soap or something? The note could be a joking way of acknowledging such a mistake.
But my money's on them simply meaning that they found the evening enjoyable and satisfying; your company is like a good meal.

refering to your dick i believe

Did you try asking around as to whom left the note? And about what? --Puzzled (Easily: But Then I'm a Guy, So It's Redundant - Lol)

No one said "Eat".

You got a note that you don't understand? You poor thing! You're in my prayers.

sounds like someone got lucky without even knowing perhaps? haha

Well, I can think of a "dirty" explanation but I'll keep it to myself. :D
