A term used when you know things about a train, plane, or the Titanic. This term can be used either as an insult, as if you are calling them a nerd, or as a complement saying that they are smart.
Friend: “how many boilers did the Titanic have?”
You: “I think like four”
Friend: “wow thanks, your such a Talish

You: “my favorite train is a TGV duplex
Annoying guy: “Wow your such a Talish you nerd!”
