An illogical conflation of two adjectives (super & excited) to describe your emotional state when you are extremely hyped-up like a a six year old child on Christmas Eve.

A word that has gained more traction in recent years and coopted by the marketing industry to get you to buy or do something.
If you do encounter anyone who is either "excited" to announce, or "super-excited" to offer you something, then run for cover and never look back.
Otherwise it means to be happy, animated, ebulliant, ecstatic, expectant, gleeful and so forth.
"We are superexcited to announce the new latex body-fitting automatic penis cleaner."
"I'm excited to advise you that your divorce is now finalized."
"Frank was superexcited to learn his wife had left town."
Ruler of Lake Titicaca. Rumored to have a bunghole that gets very angry if it does not receive toilet paper. Cornholio the Great is often seen walking around with his shirt over his head and his hands in the air, chanting songs about his power, and his bunghole.
"I am Cornholio! You do not want to face the wrath of my bunghole, for I need TP!"
Butthead: Shut up, Beavis! (uh huh huh huh)
Beavis: Um, okay. (heh heh heh heh).
