Sophia Nicole, Gang Baby

Brendan said: I told Sophia Nicole that Aunt Christine was coming to see her and she said OH!!
Richard said: But what's the meaning of the gang sign Sophia is 'throwing'???
Brendan said: That's a West Houston thing, the HBCs (the Homie Baby Cribs - they roll around our hood, usually in Big Wheels)
Jan said: I think it's more like "Oooooooh" , and the sign is "I Love You" in sign language ...
