New words?

Deplane: I am sure you’ve heard this word.
Detrain: I take a train to go to work every week. A conductor always uses this word. Is she/he imitating announcements that fight attendants use? I had never heard of this word until I began to take the train.
Defund: I heard it in NPR news. One of the legislators in Washington DC used it. In this case, “de” is combined with something other than a vehicle. Until I heard it, I thought combining “de” and a vehicle’s name is a trendy thing to do. I was wrong.

If this “trend” continues, we might eventually hear a word like:
Deschool : Graduating school.

Can you come up any other words we can combine with “de” that still make sense?
