1. Large in physical or mental maturity. Can refer to teenaged girls that are Jailbait, or boys that are Early-Bloomers, although, sexually maturity doesn't necessarily mean that said person is Big. They must also act more intelligent, mature, and responsible than their own "age-mates"

They also tend to be of high statute and are very popular

Also can be very mature teenagers that handle their own finances and assets while they are still under 18 (buying cars, selling things on ebay, making profits, etc..)

Such individuals have a large amount of trust from their own parents which in turn allows them to obtain a large amount of respect from their friends and everyone that they meet.

These are also people that are so-called "Boss"
"Yo, Jim is a Senior now, but he's bought and sold 10 different cars since he was a sophmore. Dat nigga is Big!"

"Oh my God, Sarah is only 12? I thought she was about to be 16..... She is so Big."

"Hey Mike, that's a sweet ass DC2 you got there, what happened to the civic?"

(Noun) An open-faced single condiment sandwich. Usually a delivery vehicle for that condiment, which would be impractical to eat any other way. Key is that it remain open faced, with a single ingredient (aside from the bread).

Most Common: the "Mayonnaise Big", but also a "Mustard Big", "Miracle Whip Big", "Ketchup Big" or even a "Relish Big".

Origins: PNW, Southern Oregon in the mid to late 1970's, but may date from even earlier.
I was looking for a midnight snack, and the refrigerator was nearly empty, so I had a Mayonnaise Big.

A an african american pornstar that commonly stars in many of today's sleezy porn vids, starring young and horny white women from the age of 25-40. Before any actual action, the viewer gets to listen to Big's well thought out jokes about how he will 'blow his load' and make use of his 14 inch monster cock with yet another rising pornstar. Big's sense of self worth and self esteem both rest in his massive penis that has become his primary means of income and survival. Sadly, his seduction and communication skills with other women also rest in this overlly developed penis of his.
Big stuffed his veiny 14 inch 'monster cock' into Syphylis Susan as he grunted with utter satisfaction.
