It's just another word. Like people saying "sick" to describe something they like. If you say, "yo, sick moped, dude," you're really saying "hey cowboy, your bicycle with a motor isn't running very well."
And now, language is so bastardized, that nothing means anything anymore. So if someone wants to call their car sexy, who cares?
In your posts, you typed "what in the actual fuck..." And "me being lame..."
You never have to use the word "actual" or "actually" in a sentence. Ever. Try it. Any sentence you use it in, remove it, and it's the same sentence. Only better.
And unless you are physically disabled, you're not really "lame."
