this is my first post and to be honest i don't know if what i'm gonna ask you is vulgar, i think that just because there is the word Ass, anyway i ask if no body answer to me i'll understand!1
the sentence: "soooo... here i am, feeling like a lame-ass"
thanks i found it....
"Ass" is not considered to be as vulgar as it once was. They say it on TV in the US regularly now, whereas years ago it was strictly taboo. Friends say it among themselves, but I probably wouldn't call my mom or boss a "lame ass."
