the gillis principle

The Gillis Principle outlines the proportionality between the amounts of mountain dew and marijuana that would kill an average human.

Mathematically, 1 Gillis (Gi) is the unit of either substance (Marijuana or Mountain Dew) that would kill a human when consumed within an hour. Both substances have calculated conversion rates based on experimental data.

Mountain Dew: 8823mg Caffeine = ~173 cans = 61L = 1Gi/Hour
Marijuana: 68000g THC = 971 000 Joints = 1Gi/Hour

It can be concluded using the Gillis Principle that Mountain Dew has a far higher lethality rate than Marijuana.

Friend 1: "Hey, did you hear? Jared smoked himself to death last night."
Friend 2: "Yeah that must've been a Gillis-ton of weed!"
Friend 1: "Using the Gillis Principle, that was like 971 000 Joints."

Gulbis

Ernests Gulbis, a proffesional tennis player who constantly rips the craziest shots for no reason other than to be awesome.

Gulbis is also used to describe the act of utterly humiliating someone in tennis.

to Gulbis someone: to utterly rape someone in tennis by... returning a first serve with a faster forehand, hitting a shot right at the opponent and still having the opponent whiff, smashing overheads at the opponent's face, hitting a dropshot winner when the opponent is at net, and acing someone on a 2nd serve by hitting it faster than the 1st serve.

After hitting one of these shots, a player may shout "GULBIS!!" instead of the standard "come on!"

Hey are you ready? I'm gona ace you.
-no you won't I own you
(SERVES... fault)...)
-I own you
I'm still going to ace you, right down the line
-It's ur 2nd serve, good luck
BOOM -ACE-
"GULBISS!!!!!!"
-fuck
