I am working my way through Oppenheim's Slap It and am wondering how exactly you are supposed to play the two-note "chords". The only way I can get a good tone from slapping both of them is lower my right hand so that my thumb is more or less pointing at the ceiling when I hit the strings (D and G), but I'm not sure this is what I'm meant to be doing.
I'm thinking it could be more a strumming rather than slap motion?
Honestly you're doing it right, how it feels natural.
I more or less do it the same way you do, try the strumming part, there is not right or wrong IMHO.
Just reorder that book (lost in a move )

damned teeny pinky....always hits the wrong string and makes this ugly noise.
The first half of page 15 from Mr. Oppenheim's awesome book has some great exercises for practicing both fluidity on 16th-note patterns and slapping double-stops. I don't use strumming for that. I slap both D and G string with my thumb using a downward motion.
EDIT: I'm referring to the old edition, without the tablature.
