O's in tandem,
Perhaps doublefisting liquor, where “O’s” are 40oz bottles, or 2 units of drugs where “O’s” are ounces. Or money, where “0’s” represents zeros in a bank account. Or it could be sexual, with the O’s being orgasms and his girl getting multiple “in tandem.”
O could also stand for Otis, Madlib’s first name. So he’d be saying “I’ve got Madlib with me”, and also a possible remark about the “O’s” he is so fluidly using in the above lines.
Deginitely a remark to the “O’s” used above and probably the Otis thing to also a reference to his own name DOOM.
