cougin 

The art of going out to a bar or any social establishment and picking up a woman over 30 years of age. This woman will be known as a cougar and will prefer only the company of younger men. She may or may not be good looking, but scores points because of the fact that she is most likely over 10 years older than the guy.

BB: "You cougin tonight?"
Me: "You know it.. it's Thursday night, what else do we have to do? Is mikey coming?"
BB: "Nah.. he is already out with the coug babysitting"

Cougin' it up 

Lusting after or pursuing a cougar.

Young girls don't know anything about sex, so I've been cougin' it up with the faculty.

Cougin it

Basically the phrase that embodies Wazzu's (Washington State) student population as a whole. Comes from their mascot: The cougar. It can mean anything from chokin during a sporting event (most likely) or can be used in a broad sense in that the Wazzu student is just being his/herself aka unintelligent ass-wipe.

"UW just beat Wazzu again for the Apple Cup. Haha, those morons are cougin it again."

Weed cousin 

Your cousin, usually older than you, who smokes a lot of weed. If you don't have an older brother, it is likely that your weed cousin introduced you to smoking, and that he probably did it too early. Depending on geographical relation, a high-schooler may find himself at his weed cousin's house as often as once a month, and it is common to procure cannabis from the weed cousin until one's own supply becomes secure. Usually the son of a vodka aunt.

I was off with my weed cousin last weekend... He introduced me to dabbing. And edibles. I still can't think clearly!
