The milky white glob of cum mixed with female lubrication, KY Jelly (and God knows what else) that oozes out of a woman's vagina or anus after annonymous drunken sex. When left to dry, it permenantly bonds her pubic hair to her thong.
Can also be collected after vaginal or anal intercourse for use in children's arts & crafts projects, reapairing cracked engine blocks, leaky radiators and adhering heat tiles to the space shuttle. Great dilapitory too.
NOTE: The patent for Elmer's Spoo has been purchased by the folks who manufacture Krazy Glue.
When that ho woke up this morning, her ass was stuck to the sheets with my Elmer's Spoo.
