As you know, Teddy's last name is "Towncrier." However, the term you want explained is actually two words - "town crier." Here is what town crier means as defined by Wikipedia:
"A town crier is a person who is employed by a town council to make public announcements in the streets. The crier can also be used in court or official announcements. Criers often dress elaborately, by a tradition dating to the 18th century, in a red and gold robe, white breeches, black boots and a tricorne hat.
"They carry a handbell to attract people's attention, as they shout the words "Oyez, Oyez, Oyez!" before making their announcements. The word "Oyez" means "hear ye," which is a call for silence and attention. Oyez derives from the Anglo-Norman word for listen. The proclamations book in Chester from the early 19th century records this as O Yes, O Yes!"
I don't know if that was in any way the feedback you were seeking, but it is what Wikipedia had to say.
