1) 1 of the 3 main relationship types, the others being Shawty and Girl/Boy.

Of all 3 Boo is easily the most miss used and misunderstood. Your 'Boo' originally designated "the person you fuck but don't want to be seen with..."

2) desperation fuck-buddy, that one lay you know that you can get, but really don't want to stoop to
"Oh look out son, here comes your Boo." "Oh Shit!!" ((panicked diving behind bushes, crawling for the alley, and running like mad))

To be upset or to sulk. To be miserable.

Boo stands for Booty. Men have changed the meaning so their "woman" would not be offended by having the name booty. Women do not enjoy being labeled as property and men are much smarter than people think
MAN: Hey Boo!
Woman: Awww... you are so sweet
Man: I know.

A "Boo" is a racist term for an African-American. This has two possible origins:

1. An sort of pun created from another racist name for black people: "spook".


2. An abbreviation of another racist term for blacks: "jig-a-boo".
Racist #1: "Damn, Tony did you see the lips on that boo?"

Racist #2: "Yeah, that spook had lips so big his head tipped forward".

Racist #1: Yeah, it was as long as a mule's lip from his ear down!"

Racist #2: "He was dark, too!"

Racist #1: "No kidding! That boo was so black he was almost purple!"
