I searched it up online abd it had nothing to do with manga websites but smone in the comment section of some manga that they read it on mrm? Is it a site?kr a nickname?
Well, I don't know, but if normal definitions don't work, you could always try adding 'urban dictionary' to your searches? Since I'm unsure of the context you want to know, maybe urban dictionary can give you the right answer.
I love how every comment became GET UR DIRTY ASS HANDS AWAY FROM OUR PRECIOUS xd ( still get the fk away)
