"Everything is super."
So is alles never followed by a verb? I've come across stuff like alles klar, alles gute zum Geburtstag and now alles super but I've never seen alles [verb] ...
"Geil" is very colloquial for "good/cool/great" and maybe "super". I would not really try to learn it: up to maybe 30 years ago, it only had the meaning "horny" (in the sexual sense), and somehow was then started to be used as "cool". It will sound strange when used by a foreigner.
