Well, I was born and raised in the US, and I honestly don’t have a clue what some of those mean. These do make sense (at least to me):

spring formal: A formal dance at a high school or college that takes place in the spring. Here, formal means the boys and girls dress up in nice clothes.

Underoos: A brand of kids’ underwear that usually has playful themes like Superman, Spiderman, etc.

You’re on your own for the rest!

Do you mean (the quite formal)–

Metathesize: to subject to or undergo metathesis (the transposition within a word of letters, sounds, or syllables, as in the change from Old English brid to modern English bird or in the confusion of modren for modern.

…cooloffs…

Did you mean cool off?
This is from http://dictionary.reference.com/search?r=2&q=cool%20off:

cool off

1. see cool down.
2. Also, cool down or out. Calm down, become less ardent, angry, or agitated, as in We can’t discuss it until you’ve cooled off. The verb cool alone has been used in this sense since approximately a.d. 1000; off and down were added in the late 1800s, and Davy Crockett’s Almanac (1836) had: “Resting a while, just long enough to cool out a little.”
3. Also, cool out. Kill someone, as in They threatened to cool off his brother. [Slang; first half of 1800s] Also see cool out, def. 2.

Hope this helps!

Good luck!
