Contractual Purity: After "Tha Crossroads", much to the chagrin of fans that prefer their darker, harder stuff.
Ensemble Darkhorse: There are two ways of looking at Krayzie and Bizzy's standout popularity, but which is the more correct mode is highly debatable. Either they're the darkhorses in the context of the group's popularity, or, in the context of their own popularity. Some Take a Third Option and see Flesh as the REAL darkhorse.
The group itself could qualify in the context of the Hip-Hop scene. Their success came out of nowhere, nobody expected them to last as long as they did, and this is in spite of their lack of respect from the industry.
Growing the Beard: As far as lyrics and subject matter, although there are some fans who could care less about this and would rather have the simplistic violent dark lyrics about murder.
Heartwarming Moments: Most of the time when a hip hop artist samples an older artist's work from a different genre, the most acknowledgement that original artist gets is liner note credit. When they samples Phil Collins' "Take Me Home" chorus and instrumental for their introspective song "Home", they decided to actually fly to where he was staying in Switzerland in order to feature him in the music video. Despite taking a hit when VH1 treated it as a Non Sequitur Scene, the song was popular enough in the United Kingdom and niche circles elsewhere that they decided to make Collins an honorary Bone Thug member under the name "Chrome Bone".
Magnum Opus: East. 1999 Eternal, some say The Art Of War.
Memetic Mutation: Layzie Bone's "Look what the wind blew in" Lyric became this as he recycles the verse a lot. Wish Bone's solo album that's always "Coming Soon", and the fat jokes. The Mutations have got on some fans nerves.
Newbie Boom: Post-"Tha Crossroads", and probably again after "I Tried".
Nightmare Fuel: A lot of their earlier material from Faces of Death up to The Art Of War. Specifically songs like the "Mr. Ouija" tracks, "Mo'Murder", "Hell Sent", "Sons of Assassins", etc…
