(n.) a crude smoking device, fashioned from a plastic squash bottle attached to a potato crisp tube with a hole in the end.
(v.) to smoke using a Pringleman, by inhaling smoke from a spliff
into the crisp tube reservoir (via a hole placed in the mouth of the face on the tube), before 'popping' the lid and allowing fresh air to push the smoke through the bottle and into your stoned lungs.
Peter Venkman: Hey, Spengler. Pass me the pringleman.
