What do these phrases actually mean?

Some guy had these as his screen names on msn, I have ideas what all of them mean, but I need more clarification. Please translate as many of them as possible:
* Bang bang, chitty chitty, hipz, lipz, fingertipz, ass and tittiez
* girl when we have sex, it's like we gettin rid of dandruff, because I'm grabbin ya head and shoulders
