A cooler is a somewhat insulated container where you fill it with ice and add drinks(like soda) to it. You can also add ethyl chloride to it for extra cooling power.

Cooler also means more cool.
I added ice and crush orange sodas in the cooler when I went fishing with some friends. It was awesome!

I was casterboarding! I was cooler than the other guy.

A hand in poker in which a person with a very strong hand (often the 2nd best possible hand) is beaten by the best possible hand (usually a very rare full house, four of a kind, or straight flush). The 2nd best hand is so strong that it is impossible to fold, usually resulting in the loss of a lot of money and sometimes, an existential crisis.
I wasn't letting go of my Ace-high flush. How could I put him on a straight flush? What a cooler!

The one who runs the show. What he says goes. The one who is in charge of the bouncers at a club, they see everything. Usually they earn $5000 up front, $500 a night, CASH! Yeah.
To protect my investment I've hired the best damn cooler in the business.

A term used to describe someone whow either knowingly (usually found in casinos) or unknowingly (usually in a bar) ruins a hot streak or situation.

When assosciated with the ruining of any type of foundation trying to be laid with picking up chicks, it is often accompanied by a fierce blowing wind sound caused by the offender, which in turn leads to his poor friends freezing instantaneously like cartoon characters.
