Acronym of the Chinese swear "Cao Ni Ma Bi". Literally it translates to "Fuck Your Mother's Pussy", which means (I) (will)/(want) fuck your mother or I'm your dad.

Unlike the English word of "motherfucker", which suggests incest of the object person, an user of "CNMB" shames others by flaunting itself as a (powerful) rapist/conqueror.
A: ** stay strong!
B: CNMB!
