ralpheo

(early 2010s-present, adj.) Used to describe somebody who, usually in a hyper state of mind induced by external excitement or a sugar high, starts doing too much and acting like a "kool kid" reminiscent of the trope of the precocious middle school-aged boy in mid-2000s Disney Channel movies.

Dude, when our badass cousin Jake came over yesterday, Dylan started acting totally ralpheo. When Jake was looking, he tried to do a kickflip on his skateboard while eating Cheetos and watching Nickelodeon at the same time - I guess to impress him or something.

If you find yourself vibing a little too hard with Zack from The Suite Life, you're probably ralpheo.
