A 'rumb numb bumb' is generally defined as the act of; firstly, having anal sex with a black woman for a long enough period of time as to greatly open up her anus, secondly, using a funnel (or a similar funnel-like device), one must pour alcohol (specifically rum) into the opening and thirdly, one must then drink the rum out until one's mouth is rendered numb from the alcohol.

Bill: "Dude, you wouldn't believe if I told you; I totally got a rumb numb bumb!"
when you're holding up your phone and making faces at it, as though you are taking a selfie, but you're really taking a picture of the person across from you or the wall or anything else that seems interesting but you don't want to be caught dead taking a picture of.
This action is often made more convincing by wiggling the eyebrows or opening the mouth, to pretend you're trying to get a Snapchat filter to work.
