o-zone 

Moldovan band who produced the dangerously addictive Dragostea din tei, otherwise known as the noma noma song.
There is a famous video clip of a fat boy really enjoying it that can be seen on Newgrounds etc.

Hello on a cellphone, greetings, it's me, an outlaw,
I ask you, my love, to accept happiness.
Hello, hello, it's me, Picasso,
I sent you a beep cellphone signal, and I'm brave or strong,
But you should know that I'm not asking for anything from you

Chorus from Dragostea din tei , roughly translated

O'Doul's

The most pointless beverage in the world: a non-alcoholic beer. If you're gonna drink fucking beer, take it like a man. O'Doul's actually has 0.5% alcohol, so if you can down about 100 you might feel a little buzz.

Jimmy drank 100 O'Doul's and was hospitalized for a water overdose...completely sober.

O.E.M. 

Stands for "Original Equipment Manufacturer." This refers to a company that produces hardware to be marketed under another company's brand name. You can also use the term as a verb, such as, "That Dell monitor over there is OEM'd by Sony."

For example, if Sony makes a monitor that will marketed by Dell, a "Dell" label will get stuck on the front, but the O.E.M. of the monitor is Sony.

That should impress your friends.
