The Hidden Seagull:
Secretly masturbating while watching a couple have sex, then once you've blown your load in your hand, run over to the couple and slap the semen around one of them. Seagulls do not aim when they excrete so point of contact is not overly important. You then need to run out of the room whilst making a loud seagull caww.
1. "I woke up and they were having sex right next to me!"
2. "omg what did you do?!"
1. " what any man would do in that situation, the Hidden Seagull"
