cactus cooler 

Cactus cooler is a delicious orange-pineapple soda sold in the United States, mainly California and the surrounding Southwestern states.

The soda is a bit obscure though. If cactus cooler is an option, it is the only option. Best soda there is.

Yo man, I gotta find a store that sells cactus cooler...why is this shit so rare?

Core Cooler

Laying shirtless on one's back and placing an ice cube in one's belly button. Thought of as clever by trailer trash from the Southern United States. Only effective when the user posesses a ponderous beer gut.

"Earl! Why you layin' all up in the hot sun like that?"

"It's nuthin' Martha; I got's me my core cooler"

the cooler gang 

The coolest of the cool. A gang you’ve never even seen before. They’re pretty much a bunch of jojo nerds on Instagram. The leader is @thecoolerjoseph and co-leaders @thecooleravdol and @thecoolerpolnareff. Also shoutout to @thecoolermark and @the.cooler.dosuke. They post cool content.

The cooler gang is cooler than the surreal gang

20% Cooler 

Used by the tomboyish pony Rainbow Dash in the episode "Suited for Success" of My Little Pony Friendship is Magic, it is often used by bronies to refer to something that is not cool enough.

Coolness levels can only be raised in increments of 20%, thus things can be 20, 40, 60, etc percent cooler.

Can be used to refer to temperature as well.

Example 1

Guy 1: Yo man check out Black Ops' gameplay, its amazing!

Guy 2: Meh, its ok, needs to be about 20% cooler.

Example 2

CNN reporter: The reactors are still overheating and an effort is being made to cool them.

Couch potato: Hmm they need to be about 20% cooler.
