boo
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

Boo
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".

or...

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!"
