All those words are alright to say, but if you keep saying them, then is wack. I say "uh dont know" fleuently, so its hard to catch the "uh", part.
I choose "like" cus there are a bunch of gay people over here, and they say "Like" all the time.
"like, how are you doin"
"who is like, your friend"
"we can like, hang out or something"
