at the risk of being ice picked to death....
feis, the word is 'come', not 'cum'.
'cum' is a slang spelling used solely in the sexual context ('solely' means 'only', 'context' means 'manner', 'manner' means 'way'. it can also mean 'ettiquete', like when your grandmother tells you to 'mind your manners', but that's different). i can let most rap-spellings slide, but this one is a bit much.
quatro,
i generally view it as people being too lazy to learn, so they stick to this wacky, overly simple shit and pretend that it's an accomplishment. not to say that everyone doing it is wack, there are a handful that have been doing it since '01, but anytime i see a 'new' name, with a crew beside it that i recognize, and i think 'oh, _______ must be writing that as a side name', only to find out later that it's a totally different person....i have a hard time respecting that shit. mostly i just think there's a lot of people that should thank their lucky stars that justo and esau made it cool to paint wacky shit, cause it really seems that when they came out, alot of people were like 'fuck yeah, now i don't have to try'.
