“and they have this thing called”
When telling an anecdote involving a topic that the audience might not be familiar with, it’s a good idea to lead into any technical aspect by saying something along the lines of:
“and they have this thing called x, and x basically works like this…”
It makes it much easier to follow and visualise a story this way, and gives the listener a boundary on what they need to know in order to understand your point.
On a similar topic of sentences that direct the listener/reader, James Somers notes how “It turns out” has an interesting effect on an audience by disarmingly leaping to an assumption without any rigorous testing as proof.
