Chance High 

To reach a point of being so fucking high on acid, that you need to be in your room immediately. It doesnt matter how far you are from your room either, all thought and reason dissolve when you reach this point. You usually spend the rest of the night hearing terrifying sounds.

Man i need to be in my room - Friend One
Dude we're at the lake and i'm high on LSD - Friend Two
I need to be in my room now - Friend One
You're Chance high, you shouldn't have taken two tabs of that shit - Friend Two

Dude lets take a chance and take three tabs of LSD - Guy who wants to get Chance high

High chance 

Its Low chance but opposite.
When something has a big possibility to happen.
As if something that you don't or do want to happen has a lower chance then when something other.

There is not a high chance that you are seeing this.

high speed lane change 

When a man is fornicating with a woman, and his thrust is so intense that his penis exits the vagina and is inserted into the woman's anus.

Man 1: Dude, I was banging Shelly too hard, and I accidentally got my dick in her pooper.

Man 2: Oh yeah, the high speed lane change. You gotta be careful not to cause wreckage.
