Beso really means a
sloppy, drunk bitch. But it can be used to mean slut or ho, too. For the most part, a beso is a party girl who is out of
control. It can be used playfully between
friends, but if you say it about someone you don't know it could be taken as fighting words.
The word beso originated in Albany, New York.
Paris Hilton is an example of a Beso.
You could
say: "What up Beso!" to your girl.
Or you could
see some complete
trash thatt you can't stand and wisper to your girl: ..."mega Beso"
