"Pongito ergo sum"


I looked to see if there were any English words derived from RodWard's "pongito" and was surprised to find the word "pong"
pong (rhymes with song)
vi., n.
prob. < Romany pan, to stink [Brit., etc. (exc. Cdn.) Colloq.] STINK
By "Romany" I suppose "gypsy" is meant. No Latin equivalent given.
