Shotties is the UK version of a poppa, and midlifecrisis explained it well, basically take a piece of a cigarette, put it in your metal piece thats not too big but small enought for cigarette piece to fit in without falling through, get your weed and pack it into the piece, put it in your bong and brew it slowly untill you taste a slight bit of tobacco then pull like a mutha fucka until you clear the chamber... best way is to buy a popper bong for $25 CDN straight 18" plastic and yea for someone like me its good cause they dont smell too much and i can blaze in my room without my dad getting pissed at me for smoking in the house
