Lyric discussion by tacobandit 

Just a nitpick, here. It's not necessarily about cheating on your gf or bf, at least not until the last verse. The first two versus are asking if you're down with OPP. Meaning, gettin down with someone else's gf/bf. The third verse flips it "this girl tried to OPP me" meaning she was the one down with OPP and he himself was the OPP. But the song isn't really endorsing cheating, but to take advantage of those who do cheat (heh heh still not family values but a little bit better)
