The local coffee shop I frequent recently changed their menus. Some coffee shops call the extra-large size "vasto", which is a word I think they made up. I like the word these guys made up better:
I think it would be pronounced "hyoo – jay".
Here are some more ideas I found for naming large coffee cup sizes.
i love old crown.
i want to get a big burlap sack.
i think after hyoo-jay we need to go with “bucket of love and the value of spending 4.8 hours inside old crown finishing it off”.
