The polite way to use rough words

I find out a polite way to say rough words...
which is using short-font...
just try to compare this two sentence...
and see which one is more rough...
(1)Ta Ma De who punch me...
(2)TMD who punch me...
I believe the second sentence is more polite...
so try to use short-font if u want to say bad words...
Below are some example of rough word in short-font...
DH - Diao Hai
DN - Diao NI
HK - Ham Kar
JB - Ji Bye
MH - Ma Hai
ML - Mai Lin
ND - Ngai Diao
OL - O Lin
PK - Pu Kai
HKC - Ham Kar Cha
JBL - Ji Bye Lao
PKM - Pu Ki Ma
TMD - Ta Ma De
