These are, as I recall, names of sample pregenerated characters from early D&D or AD&D modules. I think they might be from B1, In Search of the Unknown, or B2, The Keep on the Borderlands. Gary enjoyed silly and punnish PC names for pregens and characters in rules examples. My further recollection is that several of the words used there are archaic English slang. "Fonkin" and "hoddypeak" I believe both equate to "fool".
I think Supulchrave was suggesting that Gary's fondness for funny character names belies the premise that AD&D is more serious and grounded in tone.
