Lamerianish is kind of accent that related to Lammers person who can not pronounce softwarenames,especially who they have faulty lips...
Also this accent is self-explanatory as you see.
Lambering a dude is to give him a reach aroundwhile sticking a finger up his anus, pretty much like a rusty trombone except the blowing in the anus part is replaced by fingering the anus. Much like a rusty trombone, lambering produces a specific vocal music, made by the recipient, somewhat ressembling a baby sheep's bleathing, or "baaing", namely bleats, grunts, rumbles and snorts.
Guy: Is that some kind of weird techno music I'm hearing?
Girl: Nah, it's just my roomate getting his weekly lambering session.
