look up any word, like the eiffel tower:
Placing your partners head into a toilet (Similar to a swirlie) and fornucating with them doggiestyle after recently excreting feces into it. (BUT DO NOT FLUSH)
A wet brownie is a perfect way to make that prom night special, especially when you are forced to share a hotel room with several other couples and want privacy.
