Weapon eh
(Invernesian origin): Adjective used to describe something that is really agreeable. The “eh” is either added by Invernesian people for

extra emphasis because they lack expressive ability, or because they have speech impediments, or because they’re really insecure and it’s a question, “eh?” and they need reaffirmation for everything they say.

Inverness is fucking weapon eh?!

No mate, it’s really not, don’t live there unless you’re growing up, raising a family, or growing up, it’s like being trapped in a timeless void.
