A joint rolled with the butts of an ashtray full of cigarettes when someone's fiendin' smoke in their lungs. Usually occurring between 3-10 in the AM, while still awake from the previous night. The prefix bombe- is used to describe the absolute kifeness of the bombespliff.
"Chuck - dude - its 7AM, why you gotta be smokin dem bombespliffs up in here?!"
