the absolute WORST insult even god can think of. Worse than all the “ur” insults on urban dictionary combined. When u say it, a planet explodes along with the human race.

Get the ur grandma a splatmug. In the movie “Dont be a Menace to South Central While Drinking Your Juice in the Hood”, an elderly woman, the protagonist’s grandma, is messing around with the hydraulics on her 1964 Chevy Impala, and two dudes in a different car say “nice 64, grandma!”. The movie then cuts to her custom license plate, that reads “OG”. This movie is hilarious and you should watch it.
