i see ppl talking about it and im wondering what it is and if theres a way (if its somthing i might be interested in) i can learn it.

It refers to breaking down items in the Fragmentizer for Humming Power Crystals you can use to purchase items from the shop.

There's also a fantastic guide to fragging here by :D

A lot of people restock cheap junk to frag and get the crystals quicker :]

Oh ok i feel kinda dopy LOL thanks all!

Haha its okay, dont worry about it :D
