While this is indeed the name of the bad dude from mario, this word is commonly used in New Zealand when referring to the object you use to smoke marijuana when having spots. Some merely call this the spotting bottle, we, however, are more inventive.

Get the Bowser mug.
Comical term used in the context of discussing and/or conducting and exposition about the male sex organ. Originates from the comercial device used to ejaculate petrol into motorized vehicles, hence the physical metaphore at hand. "Bowser" is also misappropriated and used in reference to the smash hit video game franchise "Super Mario Brothers" however, this is in reference to a different "bowser" - an overweight antagonist war turtle.
Hey bro show us your bowser at this most inconvenient time which consists of the hours between 6pm to 8pm because thats when most modern and conventional households hold their late afternoon/evening meal.
