The Collywobbles? It is a British expression, meaning something like, 'under the weather' or 'a bit ill'. In particular, a stomach ache. But it can also indicate queasiness or slight nervousness and similar. And yes, a bit of a play on words too.
Subject: nothing in particular - whatever takes your fancy. But maybe 'get to know each other a little' could be a starting point.
I've scheduled the Event to last 90 minutes - drop in and out as you wish. I might extend my time there if it is still busy at the scheduled end.
I am uaffiliated with Hoxton Street Monster Supplies.
