Information about っちょ noun suffix


I recently encountered the suffix っちょ after a noun in a manga. According to
[Jisho](https://jisho.org/search/%E3%81%A3%E3%81%A1%E3%82%87), it is a suffix
used after a noun or the root of an adjective and which means "person who
is/thing that is".

Since it is the first time I encounter this suffix, I would like to know how
common it is and what kind of nuance it adds. How formal is it? Also, is it
regional or used everywhere in Japan? Thank you!




This is a suffix similar in purpose to English -ling or -ie, but it attaches
to only a few words. Perhaps words understood by the general public are only
先っちょ, 横っちょ and 太っちょ. Some dictionaries also list 尼っちょ and ちびっちょ as examples,
but I have never heard them. It may also appear in someone's nicknames (can be
derogatory; a recent example is ホラッチョ). It is not used in formal writings.
