So I got this entry in my copy of 成都方言
"扌笨" ben ①蘸调料:紧倒~(佐料),不嫌咸了嗦? ②扳动,扯拉:猴子逮到绳绳儿架势~。
I tried looking for this "扌笨" character:
I did a zisea.com 两分 search
with no results.
I did a zdic 字典 笔顺 search of "12131431412341" (扌 = 121 笨 = 31431412341)
with no results.
I don't think that this 马骥 is any sort of academic, of any sort, seeing as the dictionary (if you can call it that) doesn't even have any sort of tones markings or notations at all.
Maybe this character was just completely made up by the editors?
