I asked my brother to say a word starting with each letter of the alphabet with no context. This is what he said. If you're wondering what he said, so am I but here is a list of things that I think he said: A, bee, cow, dee, eee, frumplestump, grinchygoo, house, i, 10, klapsop, lappy, monty, capulets, omniscient, platypus, questionnaire, radioactive, sion, tallow, mmm, vasculatory, nnnnneaaah, xeexs, octo report, zunna
Credit to @KingPotato53 for being a good sport and spewing some nonsense right after waking up. If you want to see what my cousins would say, be sure to like and favorite.
