coaster high 

The feeling that you're still flying after you ride a coaster, or even after leaving the amusement park.
Similar to a rollergasm.

Person A: Dude, I just rode the Intimidator. I swear, I'm on a coaster high.
Person B: I know, man, I got that even after leaving the park.

Functionally High 

When a person smokes enough marijuana to feel its effects, but not enough to alter competence at regular daily tasks or create a lasting low after the effects have worn off.

Becoming functionally high is a skill that comes naturally for some, and for others takes a long time to develop and master.

Person 1: I just got some killer bud from a friend of mine. Wanna smoke?

Person 2: Ok, but I have work in an hour. I guess I'll go in functionally high.
