Upper Decker

When you take a huge dump into the water tank, hence the name upper decker.

Y'all have probably seen many more definitions and guides, but I'm gonna teach y'all how to do one even better.

1. Follow the typical steps to taking an upper decker and take all neccessary precaution to not get caught.

2. On top of shitting the most horrendous turd you can manage into the water tank, also dump in a significant quantity of high calorie food or drink (like bread, meat, highly sugary drinks, etc). This gives the microbes in the shit food to feed on, making the toilet even more nasty on top of the shit thats in there.

3. Profit

Open Decks

Open decks refer to an event or a setup where DJs can sign up for a slot to play their music without having to go through a formal booking process. These events are usually organized by clubs, bars, or other venues to provide a platform for aspiring DJs or even experienced ones to showcase their skills and music selections to an audience.

Open decks can be a great way for emerging DJs to network, gain experience performing in front of a live audience, and receive feedback on their sets. It's also a chance for audiences to discover new talent and enjoy a variety of music styles throughout the event.

Typically, open decks events are structured with designated time slots, and DJs sign up on the spot to secure a slot.
