Did it ever occur to anyone that typing dialogue is quite different and seems more intelligent and without slang than actually speaking. Therefore linguistic slang like "aint" and "ma" and even "muthaforgetin" would be unnecessary in typing dialogue. I'm 12, and as you can predict, I speak in a bit lower-vocabulary in real life than in a post.
Hence: EVEN IF Lyrical G spoke like he does in real life, his slang is obsolete in typing. This means he's actually trying to like a "gangsta frum da hood".
