The quick ducking action taken in a puclic restroom to see if any closed stalls are occupied. Often performed to assure safeness in performing a private conversation, whistling, or loud, obnoxious singing. If a duck check proves the company of another restroom-user, silence will ensue.

A snuggle duck is a drunk female that can no longer walk straight and has to snuggle up to anyone and anything in her immediate surroundings just to stay up right. Snuggle ducks are usually down to fool around, however said duck will need help waddling to the room and will most likely pass out instantly.
