Peaked

To be your best self; the time in your life when you are at your best, most successful, funniest, coolest, most popular

When you are absolutely "peaking" is to be at your prime in any activity.
This can be used to describe a person, event or group.

Peak; Bad luck, gutted. When some shit goes down that is bad on your behalf, peak for you. When something bad happens to a mate , peak for them. Effectively meaning bad luck / gutted to fuck. English street slang.

The time at which an ingested substance is at its highest possible concentration in the bloodstream. Used colloquially in the context of recreational drugs, most commonly psychedelics. When peaking, a psychedelic trip is usually at its most intense/powerful. The nature and duration of a peak varies by drug, user, and mindset at the time of tripping. Contrary to what some may say, it is not a term specific to any one particular drug.

The highest point in life that ou tard has reached, this occurred in high school for every ou tard. This peak is referring to highest point of success and that must be clarified because anytime an ou tard sees "high," they automatically associate it with weed and if we were talking about that, an ou tard would reach a new peak everyday because the only thing they do is smoke.

effectively a replacement for any negative adjective ever. could mean bad, ugly, smelly, disgusting, any of these words could be replaced by 'peak'

Euphoric feeling literally an overwhelming sensation of emotions usually good ones.
