A slang term often used by black rappers, usually in reference to attractive black women. The usage of the word in this context is largely due to the fact that the average Black man is much taller than many of the women he interacts with.
My lovie, sweetie best friend who is the best in the entire world. Every time you see her, her face lights up and she squeals, running to hug you. You would marry her, but you're not exactly gay lol.
Shawty's my best friend, don't you dare hurt her or I'll bust your face up!
