An abominable human being who creeps on others for the pure joy of just being a stalker. This person usually attains a snoopalicious high over social networking sites, most commonly Facebook. A snoopalition will tend to snatch cellular devices out of your hand mid-text, or aimlessly study a persons profile for hours on end.
"Hey, how did your sister know that my ex-girlfriend's mom is allergic to hotdogs?"
"Oh. My sister was on Facebook and told me."
"Wow. What a snoopalition."
"Tell me about it."
