You probably are thinking of a chillum. A chillum (pictured here: http://www.ukrecordshop.com/shop/ima...roductid=17378 ) is IMHO the most underrated smoking device in the world. It gets you high like a blunt with the effeciency of a pipe. Not only that, but you can pick up a great chillum usually for under 20 bucks. I don't like chillums because if you don't pack them down really tight it's possible for the weed to fall out if tilted downwards.

I used to have a nice chillum but I gave it to my friend when I got a bowl.
