Ocean City Hurricane
When a person bites both ends off a piece of Twizzlers licorice and then inserts it in another persons anus leaving a bit of the licorice exposed. They then pour fireball whiskey down the straw and suck it back out.
Things took an unexpected turn at my buddy's bachelor party when John tried to give Mark an Ocean City Hurricane. He had a hard time getting the straw to stay in since Mark and Scottie had done so much felching the night before. They almost decided to do a Kansas Tornado instead.
