First of all, stop making up words for your convenience just because you’re too lazy to say or type the whole thing. “Ima” is not a word. It really isn’t! I promise! Try using “I’m going to” instead. You’ll look more intelligent.

Also, seen isn’t a verb on its own. It’s part of a bigger, better verb! “I have seen…” sounds (and is) so much better than “I seen…” in every single case. I can’t think of any exceptions, can you?

And please, please, please stop using the entirely-too-commonly-used excuse of “I’m not in school, why do I have to use proper English?” to make your butchering of the English language acceptable. News flash: it doesn’t work! It just makes you look even less intelligent, if that’s possible.

PS: “Your a dum ass” really isn’t much of an insult. It makes you look much worse than the person you’re insulting. Really.
