Does it eat away at your insides?

[Elektrisk]

Slang is used in all languages o.O One might even consider "y'all" a slang word where you're from, but everyone says it here. I can understand if you mean people that use "u" in place of "you", or other things like that, but slang such as "slut", "yo", ect are commonly used and I don't think that they are improper. Of course, it depends entirely on how you use the word(s), but you catch my drift.
