Nicolson is a term for a friend that has your back no matter what.

A Nicholson is loyal, loving, salt of the earth, kind, funny as fuck and quite possibly an excellent lover.

To have a Nicolson is to have a rare treasure for they are few are far between.
Great nicholson's are hard to find, impossible to leave and hard to forget.

An area where beautiful women congregate. A location lusted after by men, but they can never get in.
"Oh man, I tried to get into Nicholson to see some hotties last night, but the closest I could get was to the front door."

After gaining your red wings, look up, give her your scariest grin, and growl, "Wait'll they get a loada me..." <i>re. Jack Nicholson, player of "Joker" in the movie "Batman")</i>
Did my first Nicholson last night... She didn't think it was near as funny as I did.
