Mo-toke

Verb and noun
A Mo-toke is a drag on a cigarette (or similar) in which a vast quantity is smoked at once. Not many are able take a "real" Mo toke as it is very harsh on the lungs and often makes people cough.

Mo: Can I have a drag?
Dan:Sure, just don't take a mo-toke
-Mo inhales for a good 20 seconds-
Dan: Awh! Com'on!
