"Ripping" is an activity undertaken by a rowdy and obnoxious group of men whilst drinking.
The word originated in South Wales(UK) and can be often seen when groups of 3 or more young males (stereotypically) join with hopes of having a "banging" night out.
Ripping is when someone places their index or middle finger on the webbing between their pointer and middle finger or middle and ring finger whilst pushing up against a flat surface and pulling the finger downward to create a popping noise called ripping
To take a shit or fart of God-like magnitude in a very unpleasant sounding, looking and smelling way. Typical examples can be found in public bathrooms, or after taco night.
To intend to take a short nap, but end up sleeping for a much longer period. Refers to the story of Rip Van Winkle who fell asleep for a hundred years.
I meant to take a quick nap before my next class but I ended up ripping a van winkle and missing my midterm.
