This one's been going around for awhile, and it took me most of that time to come up with all the descriptions:

Pick up to 15 OTPs.
Describe them in 15 words or less.
Have your flist guess the OTP.

1. The adorable true love of a chipmunk and a pickle. Ch'p/Salakk aka Salaak, guessed by rayshell22, who can't spell Ch'p, and harmonyangel, who can't remember either of their names...
2. He went to California for his man and it was all downhill from there. Guy/Hal, guessed by mari_redstar.
3. Going to Qward in his jacket on the back of his motorcycle! Guy/Lobo, guessed by poisonivory.

5. Fifth dimensional fanboys. Bat-Mite/Mr. Mxyzptlk, guessed by ilyena_sylph and bats_eye.

7. "Guess I'm just a freak of nature. Want to go to the dance?"
8. It's alllllll about the nicknames. Well, and fighting Nazis. Namor/Original Human Torch, guessed by bats_eye.
9. You can tell it's true love when you start building robots in your sleep. Brainiac 5/Supergirl, guessed by mari_redstar.

12. When this relationship went badly, somehow Harry Osborne got attacked. Cap/Falc, guessed by harmonyangel.
13. Because dark and broody clearly needs bright, funny, and flexible. Plastic Man/Batman, guessed by odditycollector.
14. True love is being someone's umbrella in the rain and hammock at night. Is not actually Ralph/Sue, but lilacsigil gets partial credit anyway, because they totally got left out of the meme unjustly.
