In the second verse at a bout 1:22 she starts playing a really cool slap strum technique. I have been listening to that video for over a year now and I am still not good enough to copy it exactly!

If you guys could help me out with this I would be very grateful. I've asked almost everybody I know and have posted this on other forums as well.

Please don't tell me to try to figure it out myself because I have tried. I swear to god I have tried.

Thanks guys.
shes basically just using her nails to slap the strings/body just to create that clicking sound to keep time and add a little color
she's doing the plucking and then at the end of the bar, shes slapping, but running all her nails along the strings right before?
Just tap your foot searching for the 1+2+3+4 beat, she hits the strings on 2 and 4 to get that groove going. As for the chords, the picking pattern is also simple, just listen to the song, learn the chords and accentuate them as the groove suggests.
