Similar to a dutch oven, it is the act of trapping a fart inside and then smothering someone with the stench while wearing a snuggie.
I know I look ridiculous in a Snuggie, but it was worth it just to give Rachel a Roncho Poncho last night.
killing mass amounts of people with a chainsaw in each hand and wearing a burlap sack with two eye holes cut out.
i went roncho poncho on a welfare line.
