I find your colleagues confusing. To me, "huge" seems bigger than
"large". I don't seem to be the only one:

https://www.quora.com/What-is-the-difference-among-big-large-huge-enormous-and-giant
(for example)

Perhaps the problem is that people have turned "THP" into a thing in its
own right. So they feel comfortable talking about small THP, medium THP
and large THP and ignoring that there's already a "huge" embedded in THP.

Now if you'll excuse me, I have to put my PIN number into the ATM machine.
