I`ve been listening to the song and keep hearing this strange slide thing going, which sounds kind of like this:
B--5s4s5-------------------
If you hit the 5 a little hard, then drag your finger to the four and back to the five without striking the string again with your strumming hand, it should produce that sound.
p == pull s == slide h == hammer-on v == vibrato
