british, the act of throwing buds of plants at windows of peoples homes just for kicks. Plant buds favoured because stones/rocks smash and eggs splat, allows one to be a little bugger whilst not being a complete shit. Plus, plant buds are to hand when roaming the street with ones friends. Repeated visits to the same house cause maximum annoyance, often resulting in getting chased by the homeowner!!!
"shall we go budding?" "most def, grab that plant bud and throw it at mrs smith, pain in the arse she is!!"
