person 1 : omg did u hear about that guy on roblox?
Japanese Vocaloid producer turned singer-songwriter. Became popular due to his impressive vocal range and the ability to sing in a high, feminine voice. Vocal equivalent of a trap.
"Mafumafu's voice is great. I bet she's super cute."
The Mafren is basically when someone ignores the chateven when people are addressing them cause they think they'll be accused of being a bitch (cause they are a bitch)
