When someone who still lives with their parents has a marijuana session before going to bed. To pull off a successful before-bedder, one needs a Bounce-blower in order to cover the incriminating scent. It is recommended that the person performing the before-bedder go under their covers (with their pipe or bong, etc., as it is not as effictient with a joint), and after taking a rip, cover the bowl with their hand and then breathe through their Bounce-blower and into a shirt (the shirt is used to absorb the scent). Afterward, it is wise to watch TV (if you have one in your room); watch a comedy show, or movie, if you have the means.
Alex was too scared to have a before-bedder until Joe told him that he had had one in his parents' bedroom after they had gone to sleep.
