Dies - Pool Party
Swimming and partying!
  • You are invited to a party! I am however, not going to tell you what we are going to do. I have contemplated about it, but I'd rather have it stay a mystery until you have arrived at said party. This means that, although you are invited, you will have to make creative guesses as to the activity we are going to undertake. I have taken all possible precautions to keep you from gaining any more knowledge about the upcoming activity. I am truly sorry to keep you in the dark.

    Oh, one more thing. Remember to bring your swimming clothes. 😋🏊‍♀️🩳🩱

    YES YES! As you might have already guessed, it is time for a POOOL PARTAY! Hand us six smooth Euro coins (€6) and we'll hand you a swimming pool. And a party.

    Friday April 19th, starting at 21:00, we'll have an amazing pool party at Zwembad Poelmeer, Langevoort 273, 2343 CE Oegstgeest. (The FooBar wasn't available for this.)

    It will be good vibes all around, with a bar next to the pool and your friends, well, in the pool. Bring them along and sign up. Quick!
    See you there!

RvS Barbecue
Winnie the Pooh with the Council of Senators
  • Deep in the 101 Acre Woods, little piglet was walking around merrily. He was on his way to his friend Owl, for a nice long discussion. But the 101 Acre Woods are not safe from the dangerous Pooh, Rabbit, Tigger, Eeyore, Kanga and Roo. They kidnapped Piglet... and put him on the BBQ!

    On Monday the 22rd of April, come join us on the long-awaited, legendary, amazing RvS Barbeque, and help us roast Piglet. Of course, for the herbivores among us there will also be vegetarian options. The BBQ starts at 6, and will cost at most 9 euros.

Dies - Cavantus
A cantus, but then slightly different
  • Huh, what is that activity everyone is so excited for? A cavantus? I don't know that word! Don't worry, I've looked up the formal definition of a cavantus for you.

    Meaning of 'Cavantus'
    /ka'vɑn.tʏs/ (plural: cavantus)

    1. Merger of the words 'cava' and 'cantus', which implies the execution of a cantus using cava.
    2. Recipe for diesaster.
    3. A beautiful activity organised by the dies committee as a magnificent finisher of the dies weeks. In this activity, the attendees sing while the praesidium keeps them in check. Other than that, generous amounts of drinks are consumed, with a choice between cava and children's champagne. It comes paired with enjoyment and delight, and delivers a magnificent evening for all.

    An example in practice:
    "The cavantus of the 26th of April in the FooBar not only is really fun, it also costs €6 at most!"
