The act of laying down a tarp out of necessity after having not ejaculated for an exuberant amount of time. So much stored semen results, that if one didn't lay aforementioned tarp it would result in either nocturnal emissions or property damage.
Eric: Dude, I haven't jacked off in like a week...I think tonight's the night.
Pat: Well man if this is anything like Bukkake Sunday you better be laying tarp.
Eric: Yea man, I want to get back my security deposit too.
