gn'r lies! i know its fullish to ask but what they lie about?

Answer 1

I don't think it meant G'n'R was lieing. If you recall the cover looked like a collage of tabloid headlines. And Axl always had a problem with the media supposedly telling lies about G'n'R (listen to Get in the RIng).

So I'd wager it is a shot at the media for telling lies about them, and lies in general, to promote sales.

Answer 2

My impression is that the title and album art were the band's way of "poking back" at tabloid gossip and rumors surrounding them at the time.

Answer 3

Every song on the album is a lie, ok ok il kidding, I dunno what is up with the title
