a weed smoking device as opposed to a bong (bong without gores)

A tutor is not a "bong." A tutor is similar to a teacher, except unlike a teacher, a tutor is able to offer students one-on-one attention and actually explain difficult concepts so that they make sense.

Tutors are often students themselves, volunteering their time to fulfill one or more of these objectives:
a) Fill their resumes or
b) Actually help kids or
c) Make money

Whether in it for a, b, or c, most tutors know what they're doing.

Someone who puts your brain into work mode,so that you know what to do in the future.

A type of weedsmoking device that is similar to a bong but made without a gauze. The usual method is cutting a square of tin from a can, rolling it up and taping it together. This is then inserted into a plastic bottle with a little water in it. A plug of tobacco is pushed down the pipe and the weed or resin is put on top of it. A hit hole is made in the side of the bottle and the user inhales until the whole plug is burning profusely, at which point the hit hole is released and the plug is sucked through down into the water. This causes a lot of smoke to be inhaled at once.
