There are lots

Judicial estoppel - Being barred taking positions directly the opposite of ones you've taken in litigation before (and benefited from). IE you can't say "we didn't do it" in a civil lawsuit, and then say "we did do it" in a bankruptcy proceeding.

Estoppel by deed - In real estate, f i give you a deed to a house, i can't later turn around and claim it wasn't a valid deed.

Prosecution history estoppel - in patents, if i disclaim something in a proceeding with the PTO to get a patent, i can't later claim infringement for the thing i disclaimed.

IE if the USPTO gives me a prior art reference and says it overlaps, I can say "my patent doesn't cover that" and disclaim rights to the part they think overlaps. I can't later sue someone over that overlap.

This was super helpful and easier to understand than the wiki page. Thanks for taking the time to writing these!

Sure.

One thing to keep in mind is that there are lots of nuances being lost in what i write - they are just generalizations
